Bel Canto is the fourth novel by American author Ann Patchett, published in 2001 by Perennial, an imprint of HarperCollins Publishers. It was awarded both the Orange Prize for Fiction and PEN/Faulkner Award for Fiction. It was placed on several top book lists, including Amazon's Best Books of the Year (2001). It was also adapted into an opera in 2015.

Based on the Japanese embassy hostage crisis (also called the Lima Crisis) of 1996–1997 in Lima, Peru, the novel follows the relationships among a group of young terrorists and their hostages, who are mostly high-profile executives and politicians, over several months. Many of the characters form unbreakable bonds of friendship, while some fall in love.
