Joinville Island lies in Graham Land to the east of the tip of Trinity Peninsula, which is itself the tip of the Antarctic Peninsula.
The Antarctic Sound separates it from the Trinity Peninsula.
D'Urville Island is to the north, Danger Islands to the east and Dundee Island to the west.
Northern features include Cape Kinnes, Boral Point, King Point and Fitzroy Point.

Sailing directions

The US Defense Mapping Agency's ''Sailing Directions for Antarctica'' (1976) describes Joinville Island as follows:

Discovery and name

Joinville Island was discovered and charted roughly during 1838 by a French expedition commanded by Captain Jules Dumont d'Urville, who named it for François d'Orléans, Prince of Joinville (1818–1900), the third son of Louis-Philippe, Duke of Orléans.

Northern features

Features in the north of the island, from west to east, include:

Cape Kinnes

.
A cape which forms the west extremity of Joinville Island, off the northeast end of Antarctic Peninsula.
Named by members of the Dundee whaling expedition 1892–93, for R. Kinnes, sponsor of the expedition.

Madder Cliffs

.
Reddish rock cliffs rising steeply from the sea to about high and forming the north side of the entrance to Suspires Bay, at the west end of Joinville Island.
Surveyed by the Falkland Islands Dependencies Survey (FIDS) in 1953-54.
The name, given in 1956 by the UK Antarctic Place-Names Committee (UK-APC), is descriptive of the red color of the rocks, madder being a red vegetable dye.

Suspiros Bay

.
A small bay indenting the west end of Joinville Island just south of Madder Cliffs.
The name was proposed by Captain Emilio L. Díaz, commander of the Argentine Antarctic task force (1951-52).
The toponym alludes to the difficulties encountered in surrounding the bay.

Balaena Valley

.
A gently sloping valley, filled with ice, lying east of Suspires Bay in the west part of Joinville Island.
Surveyed by the FIDS in 1953-54.
The Balaena (Alexander Fairweather, master) was one of the Dundee whaling ships that visited the Joinville Island group in 1892-93.
The name was applied in 1956 by the UK-APC and derives from association with Cape Kinnes to the SW; Robert Kinnes was the Dundee shipowner and merchant who equipped these ships for their Antarctic voyage.

Saxum Nunatak

.
An isolated nunatak, high, standing north of Mount Tholus on the north side of Joinville Island.
It is dome-shaped when seen from the south, but has a conspicuous rock wall on its northern side.
Surveyed by the FIDS in 1954.
The name is descriptive of the feature as seen from the north, "saxum" being Latin for wall.

Gaviotín Rock

.
A rock lying in Larsen Channel, about north of the coastal ice cliffs of Joinville Island and north of Saxum Nunatak.
The name Gaviotín (gull) appears on an Argentine government chart of 1957.

Boreal Point

.
A point forming the west side of Rockpepper Bay, along the north coast of Joinville Island.
Surveyed by the FIDS in 1953-54.
The feature was so named by the UK-APC because of its position on the north coast of Joinville Island.

Rockpepper Bay

.
A bay wide at its entrance, lying east of Boreal Point along the north coast of Joinville Island.
Surveyed by the FIDS in 1953-54.
So named by the UK-APC because of the very many small islands and rocks in the bay.

King Point

.
A point marking the west side of the entrance to Ambush Bay on the north coast of Joinville Island.
Discovered on December 30, 1842 by a British expedition under Ross, who named it Cape King for Captain (later Rear Admiral) Phillip Parker King, RN, 1793-1856, English naval surveyor who made notable improvements to the charts of Australia and South America.

Ambush Bay

.
A bay wide indenting the north coast of Joinville Island immediately east of King Point.
Surveyed by the FIDS in 1953.
The name arose because the bay is a trap for the unwary if its shallow and foul nature is not known.

Fliess Bay

.
A bay lying immediately west of Fitzroy Point along the north coast of Joinville Island.
The name appears on an Argentine government chart of 1957.
Named "Caleta Almirante Fliess" after Admiral Felipe Fliess (1878-1952) who, as a lieutenant, was commander of the Argentine navy group detached for duty with the crew of the ship Uruguay in 1903, on the occasion of the rescue expedition to the members of the SwedAE (1901-04) led by Doctor Otto Nordenskjold.

Fitzroy Point

.
A low point at the east side of Fliess Bay forming the northeast extremity of Joinville Island.
Discovered on December 30, 1842 by a British expedition under James Clark Ross, who named it Cape Fitzroy for Captain (later Vice Admiral) Robert Fitzroy, RN (1805-65), English hydrographer and meteorologist.

Southern features

D'Urville Monument

.
A conspicuous conical summit, high, at the southwest end of Joinville Island.
Discovered by a British expedition, 1839-43, under James Clark Ross, and named by him for Captain Jules Dumont d'Urville.

Diana Reef

.
An isolated reef lying east of D'Urville Monument, Joinville Island, in Active Sound.
Roughly surveyed by FIDS in 1954.
Named in 1956 by UK-APC after Diana (Robert Davidson, master), one of the ships of the Dundee whaling expedition which visited the Joinville Island area in 1892-93.

Nodule Nunatak

.
A small but prominent isolated nunatak, high, standing south of Mount Tholus in the southern part of Joinville Island.
Surveyed by the FIDS in 1953-54. The descriptive name was given by the UK-APC in 1956.

Mount Tholus

.
The highest mountain, high, in the ridge extending southwest from Postern Gap in the central part of Joinville Island.
Surveyed by the FIDS in 1953-54 and named by the UK-APC in 1956.
The name is descriptive, "tholus" being a circular, domed structure.

Postern Gap

.
A pass in the central ridge of Joinville Island, just east of Mount Tholus.
Surveyed by the FIDS in 1954.
So named by the UK-APC because this is the only way through the ridge which gives access to the central part of the south coast of Joinville Island.

Gibson Bay

.
A small bay on the south side of Joinville Island, lying just west of Mount Alexander at the junction of Active Sound and the Firth of Tay.
Discovered and named on January 8, 1893 by Thomas Robertson, master of the ship ''Active'', one of the Dundee whalers.

Mount Percy

.
A prominent mountain, high, the highest feature on Joinville Island, standing immediately north of Mount Alexander near the center of the island.
Discovered by a British expedition under Ross on December 30, 1842, and named for Rear Admiral the Honorable Josceline Percy, RN, 1784-1856.
Although this mountain is not surmounted by twin peaks, as described by Ross, there are a number of peaks of similar height in its vicinity, one of which may have given rise to Ross' description.

Mount Alexander

.
A mountain with several summits, the highest high, forming the rocky peninsula separating Gibson Bay and Haddon Bay, on the south side of Joinville Island.
The cliff marking the extremity of the peninsula was discovered and named Cape Alexander on January 8, 1893 by Thomas Robertson, master of the ship Active, one of the Dundee whalers.
The name was amended to Mount Alexander by the UK-APC in 1956 following a survey by the FIDS in 1953-54, the mountain summits of the peninsula being considered more suitable to name.

Haddon Bay

.
A bay lying immediately east of Mount Alexander along the south coast of Joinville Island.
Discovered in January 1893 by Thomas Robertson, master of the ship Active, one of the Dundee whalers.
Surveyed by the FIDS in 1953 and named by the UK-APC in 1956 for Professor Alfred C. Haddon (1855-1940), who helped Doctor W.S. Bruce with his preparations for scientific work with the Dundee whaling expedition.

Mount Quilmes

.
A mainly snow-covered mountain, , standing northeast of Haddon Bay.
The name was given during the course of the Argentine Antarctic Expedition (1953-54) and memorializes the battle of the same'name in which the Argentine squadron of Admiral Guillermo Brown was engaged.

Tay Head

.
A rocky headland east of Mount Alexander, extending into the Firth of Tay on the south coast of Joinville Island.
The name, given by the UK-APC in 1963, is derived from the Firth of Tay.

Moody Point

.
A point which forms the east end of Joinville Island.

Williwaw Rocks

.
Two small rocks lying south of Moody Point.
Surveyed by the FIDS in 1953.
The name arose because williwaws appear to be characteristic in the vicinity of Moody Point and the nearby Danger Islands.

Scud Rock

.
An isolated rock lying south of Moody Point.
