Portal Reloaded is a 2021 mod for the 2011 puzzle-platform game Portal 2, developed and published by Jannis Brinkman. As in the official Portal series, gameplay involves solving puzzles by manipulating portals, which allow the player to move through chambers. The mod also allows the player to shoot a third "time portal", allowing traversal across two versions of the puzzle chamber in different time periods. The player assumes control of a test subject who has to complete puzzles inside the Aperture Science Enrichment Center and destroy a "rogue test subject".

The development of Portal Reloaded began in 2014, initially envisioned as a smaller project. Portal Reloaded was released on Steam for free on April 29, 2021, as a full-scale mod featuring a custom soundtrack and story. A 2023 update introduced a co-op mode to the game. Portal Reloaded received largely positive reception from reviewers, who praised its puzzle designs and humor.
