This is a selected list of Source engine mods (modifications), the game engine created by Valve for most of their games, including ''Half-Life'', ''Team Fortress 2'', and ''Portal'', as well as licensed to third parties. This list is divided into single-player and multiplayer mods.

Single-player mods

* '' Aperture Tag'' - A modification based on ''Portal 2'' that recreates the essence of the game '' Tag: The Power of Paint'', the inspiration for the various gels used in ''Portal 2''. Instead of a portal gun, the player solves puzzles using a mix of these gels that they can spray onto surfaces with a tool they carry.
* '' Black Mesa'' - A third-party recreation of ''Half-Life'' (1998) that was made in response to the release of '' Half-Life: Source'' (2005), a port of the original game to the Source engine. ''Black Mesa'' originally released as a free mod in September 2012, and later had a full commercial release on Steam in March 2020.
* ''Coastline to Atmosphere'' - A mod set in the ''Half-Life 2'' universe, following Gordon Freeman after the events of ''Half-Life 2''.
* ''Dear Esther'' - An experimental "ghost story" created as a research project at the University of Portsmouth; initially released as a free modification in 2008, a longer commercial version was developed and released in 2012.
*'' Flipside'' - A side-scrolling platform game that allows the player to "flip" the game world around to its backside, altering the means a player can traverse a level.
* ''Jurassic Life'' - A modification based on the first ''Jurassic Park'' film. The game acts as a side story to the movie where the player takes the role of the park's game warden, Robert Muldoon.
* '' Korsakovia'' - A single-player mod for ''Half-Life 2''. It was developed by The Chinese Room and released September 19, 2009. In Korsakovia, the player travels through the delusions of Christopher, a man suffering from Korsakoff's Syndrome. The player hears the voices of Christopher and a doctor as they try to work out what is wrong with Christopher.
* ''Minerva'' - An episodic single-player mod based in the ''Half-Life 2'' universe, using storytelling inspired by classic games such as ''Marathon'' and ''System Shock''.

* ''Portal: Prelude'' - An unofficial prequel to ''Portal'', set before the activation of GLaDOS when scientists used to watch over the test chambers and instruct the test subjects.
* ''Portal Reloaded'' - A mod atop ''Portal 2'' that introduces the ability to place a third portal that sends the player-characters or objects through between the present and a future state of the same test chamber. Actions in the present state will alter the future, though manipulation of the future situation will not impact the present, allowing, for example, for one to bring a weighted cube set in the present from its position in the future, back through the time portal, and use that version of the cube in the present.
* '' Portal Stories: Mel'' - A mod build on ''Portal 2'', in which the player controls Mel, who was a character that Valve had originally designed for ''Portal 2''s cooperative mode. The mod takes place after events of ''Portal'' and before the events of ''Portal 2''.

* ''Research and Development'', a "non-combative" modification that has been likened to ''Portal'', in which the player uses the gravity gun and other aspects of the Source engine physics to solve puzzles and progress forward.
* ''Rexaura'', a ''Portal'' modification, with puzzles designed around manipulating and ricocheting plasma balls.
* ''Riot Act'' - A mod set in the ''Half-Life 2'' universe, following a member of the civilian resistance on their escape from the Combine prison at Nova Prospekt.
* ''Operation Black Mesa'' - A remake of the Half-Life expansion Opposing Force developed by Tripmine Studio.
