The award is presented annually by the website RottenTomatoes.com, which compiles reviews from critics to measure the percentage of favorable critiques.
Editor-in-chief Matt Atchity says Pixar's animated tale about toys searching for meaning when their owner grows up and heads off to college collected positive reviews from 99 percent of critics, making it the best-reviewed film in wide release of 2010.
"Toy Story 3" beat out "The Social Network," which got a positive-review score of 97 percent and took the Tomato in the drama category.
Other Golden Tomato winners announced Tuesday include the rebooted Western "True Grit," the Banksy documentary "Exit Through the Gift Shop" and "Last Train Home," a documentary about Chinese migrant workers.
