Teenage Mutant Ninja Turtles: Turtles in Time Re-Shelled (sometimes shortened Turtles in Time: Re-Shelled) is an enhanced remake of the 1991 arcade game, Teenage Mutant Ninja Turtles: Turtles in Time, which itself is a sequel to the original Teenage Mutant Ninja Turtles arcade game. Both of the original arcade games were produced by Konami. It is a side scrolling beat 'em up based on the 1987 animated series.

It was developed and published by Ubisoft Singapore for the PlayStation 3 and Xbox 360. It was released worldwide on August 5, 2009 on Xbox Live Arcade and September 10, 2009 on the PlayStation Network. The game was later delisted from the Xbox Live Marketplace and the PlayStation Store in June 2011, due to an expired license.

The game was a commercial success, moving more than 444,000 units during its time on Xbox Live Arcade. It also was the top downloadable title on the North American PlayStation Network the month of its release. Despite high sales, critical reception was mediocre overall. The PlayStation 3 version holds a score of 56.50% at GameRankings, while the Xbox 360 version holds a score of 61.79%. Reviewers generally praised the enhanced visuals and addition of online play, but were critical of the little replay value and the inability to join a game already in progress.
