Operation Red Sea (Chinese: 红海行动) is a 2018 Chinese-Hong Kong action war film directed by Dante Lam and starring Zhang Yi, Huang Jingyu, Hai Qing, Du Jiang and Jiang Luxia. The film is loosely based on the evacuation of foreign nationals and almost 600 Chinese citizens from Yemen's southern port of Aden during late March in 2015 Yemeni Civil War. According to Chinaculture.org, the film is in similar style to that of Operation Mekong.

It serves as the highlight film presented to audiences as a gift for the 90th anniversary of the founding of the Chinese People's Liberation Army, as well as the party's 19th National Congress. This film is said to be "China's first modern naval film". The film has grossed USD$579 million, and received critical acclaim from critics, making it currently the eleventh-highest-grossing ever in China and highest grossing Chinese film in 2018. It was selected as the Hong Kong entry for the Best Foreign Language Film at the 91st Academy Awards, but it was not nominated.

A sequel, Operation Leviathan, has been released in 2025.
