Time Squad is an American animated television series created by Dave Wasson for Cartoon Network and the tenth of the network's Cartoon Cartoons. It follows the adventures of Otto Osworth, Buck Tuddrussel, and the robot Larry 3000, a trio of hapless "time cops" living in the far distant future who travel back in time attempting to correct the course of history. During their adventures, they run into major historical figures such as Julius Caesar, Abraham Lincoln, Sigmund Freud, Leonardo da Vinci, the Founding Fathers, and Moctezuma, who have taken a drastically different course of life than history dictates. The mission of the Time Squad is to guide these figures onto the correct path and ensure the integrity of the future.

The series premiered during Cartoon Network's marathon block "Cartoon Cartoon Summer" on June 8, 2001, and ended after two seasons on November 26, 2003, airing 26 episodes in total. In the course of its run, the series received five Annie Award nominations. Creator Dave Wasson described the series as "a C-average student's approach [to history]—a CliffsNotes version of what historical characters did and giving it a twist." It is the final Cartoon Network original series to premiere during Betty Cohen's tenure, as she later resigned due to creative disagreements with Jamie Kellner, then-head of Turner Broadcasting System. Cohen was eventually replaced with Jim Samples ten days after Time Squad premiered.

Time Squad was the first Cartoon Network original series to be entirely produced by Cartoon Network Studios, no longer a division of Hanna-Barbera following the death of William Hanna in 2001. The show began airing on Canada's Teletoon Detour block in 2002. The show features music from Michael Tavera, who would later make music for ¡Mucha Lucha!, Lilo & Stitch: The Series, Yin Yang Yo! and The Secret Saturdays.
