Spies in Disguise is a 2019 American animated spy comedy film produced by Blue Sky Studios and distributed by 20th Century Fox. Loosely inspired by the 2009 animated short Pigeon: Impossible by Lucas Martell, the film is directed by Troy Quane and Nick Bruno (in their feature directorial debuts) from a screenplay by Brad Copeland and Lloyd Taylor, and a story by Cindy Davis. It stars the voices of Will Smith and Tom Holland, alongside Rashida Jones, Ben Mendelsohn, Reba McEntire, Rachel Brosnahan, Karen Gillan, DJ Khaled, and Masi Oka in supporting roles. The plot follows a secret agent who is transformed into a pigeon by an intelligent young scientist; the two must then work together to stop a revenge-seeking cybernetic terrorist, and return the agent to his human form.

The film premiered at the El Capitan Theatre on December 4, 2019, and was theatrically released in the United States on December 25, 2019. It received generally positive reviews from critics, with praise for the animation, music, humor, and vocal performances (particularly Smith and Holland). However, the film was a box office disappointment, grossing $171.6 million worldwide against a $100 million budget.

The film was the last film to be produced by Blue Sky Studios, as well as the only animated film from 20th Century Fox and Blue Sky Studios after the acquisition of 21st Century Fox by The Walt Disney Company, and the last animated film to use the 20th Century Fox name.
