Cast

The cast features 14 major roles with star billing, all of whom return from the fourth season. Because the storyline follows two different time periods, the cast is largely broken into two groups. The first storyline follows the group of people who have left the island: the survivors' leader Dr. Jack Shephard ( Matthew Fox), ex-fugitive Kate Austen (Evangeline Lilly), mentally unstable millionaire Hugo "Hurley" Reyes (Jorge Garcia), former torturer Sayid Jarrah (Naveen Andrews), grieving wife Sun-Hwa Kwon ( Yunjin Kim), three-year islander Desmond Hume ( Henry Ian Cusick) and Ben Linus ( Michael Emerson), former leader of the island's native population, known as the Others. The second follows those who remain on the island as they erratically jump through time, following the island being moved in the fourth-season finale. They are crash survivor and con man James "Sawyer" Ford ( Josh Holloway), former Other and fertility specialist Dr. Juliet Burke ( Elizabeth Mitchell), crash survivor and former enforcer Jin Kwon ( Daniel Dae Kim), who survived the explosion of the freighter, and three members of a science team from a freighter offshore, who have joined the crash survivors: medium Miles Straume ( Ken Leung), anthropologist Charlotte Lewis (Rebecca Mader), and physicist Daniel Faraday ( Jeremy Davies). The only main character to be involved in both storylines is John Locke (Terry O'Quinn), who, at the end of the fourth season, leaves his fellow crash survivors to become the new leader of the Others. However, following the first jump through time, he rejoins the crash survivors and eventually leaves the island and dies, which prompts the other survivors who have left the island to return with his body. The character of Charlotte is written out in the fifth episode of the season, as well as Faraday in the fourteenth and overall one hundredth episode.

Those who previously received star billing in season four, but did not in season five include Claire Littleton ( Emilie de Ravin), who followed an apparition of her deceased father into the forest and later appeared in Jacob's cabin and Michael Dawson ( Harold Perrineau), who died when the freighter exploded. Emilie de Ravin returned as a regular cast member in season six. Furthermore, former main cast member Malcolm David Kelley, who portrays Walt Lloyd, Michael's son, makes guest appearances in the fifth season. Second season main cast member Michelle Rodriguez portrays the deceased Ana Lucia Cortez in one episode.

Several of the guest stars from past seasons reprise their roles in season five. Nestor Carbonell appears as the apparently ageless Richard Alpert in nine episodes; Cheech Marin returns as Hurley's father, David Reyes; François Chau portrays Dharma Initiative scientist Dr. Pierre Chang; Lance Reddick continues to appear as the mysterious Matthew Abaddon; Sonya Walger plays Desmond's wife, Penny Widmore; William Mapother portrays deceased Other Ethan Rom; Jeff Fahey returns as pilot Frank Lapidus; and L. Scott Caldwell and Sam Anderson continue to play married couple Rose Henderson and Bernard Nadler, respectively. Recurring guest stars Alan Dale and John Terry who play billionaire Charles Widmore and deceased Christian Shephard, respectively reprise their roles. The character of Danielle Rousseau is present in the fifth season as a younger version, played by Melissa Farman. Mira Furlan, who previously portrayed an older Rousseau, asked for her character to be written out of the series because she did not want to travel to Hawaii to film her scenes. Tania Raymonde returns as her daughter, Alex. Fionnula Flanagan also returns as Eloise Hawking. Patrick Fischler plays Phil, a member of the DHARMA Initiative. Brad William Henke portrays Bram, a survivor of Ajira Airways flight 316. Sterling Beaumon reprises his role of young Ben for four episodes in the second half of the season. Marsha Thomason also returns briefly as Naomi Dorrit. The final recurring character is Vincent, Walt's yellow lab. The producers stated that Vincent survives to the series' conclusion.

Several new recurring characters are introduced in the fifth season. Two characters introduced in the premiere are Lara, Dr. Chang's wife and Miles' mother, who is portrayed by Leslie Ishii, and Dan Norton, an attorney who is given the task of performing a maternity test on Kate and Aaron, portrayed by Tom Irwin. Another pair of recurring characters, Caesar played by Saïd Taghmaoui and Ilana, played by Zuleikha Robinson, are introduced in the sixth episode, " 316". Ilana was upgraded to the main cast in the sixth season. Reiko Aylesworth guest-stars in three episodes as Amy, a member of the Dharma Initiative, a scientific group that did research on the island in the 1970s. Eric Lange portrays Radzinsky, a member of the Dharma Initiative, in seven episodes. Two new recurring characters appeared in the fifth-season finale: Jacob, the well-known and unseen leader of the Others, played by Mark Pellegrino, and his unnamed nemesis (nicknamed "Samuel" in the casting call), whom Ausiello likened to J. R. Ewing and is portrayed by Titus Welliver. Sean Whalen, who previously portrayed Neil Frogurt in the '' Lost: Missing Pieces'' mobisodes
