Between 12 January 2024 and 6 May 2025 the United States and the United Kingdom, with support from Australia, Bahrain, Canada, Denmark, the Netherlands, and New Zealand, launched a series of cruise missile and airstrikes against the Houthi movement in Yemen in response to Houthi attacks on ships in the Red Sea. The Houthis had previously declared that their attacks were in support of Palestinians during the Gaza war; Houthi attacks on shipping were condemned by the United Nations Security Council the day before the initial strike.

The first phase of attacks between January 2024 and January 2025 were codenamed Operation Poseidon Archer. US President Joe Biden ordered the strikes, and UK Prime Minister Rishi Sunak convened his cabinet to authorize British participation. American officials said the strikes were intended to degrade Houthi capabilities to attack Red Sea targets rather than to kill leaders and Iranian trainers. By 2 January 2025, the Houthis recorded 931 American and British airstrikes against its sites in Yemen, resulting in 106 deaths and 314 injuries. The strikes were halted during much of the January 2025 Gaza war ceasefire, which lasted from January to March.

Airstrikes resumed between 15 March and 6 May 2025, under the codename Operation Rough Rider. US President Donald Trump ordered the operation with over 1,000 airstrikes having been conducted by the end of April, with UK Prime Minister Keir Starmer authorizing strikes as well. On 6 May, Trump declared the strikes to be over as a result of a ceasefire reached between the United States and the Houthis, brokered by Oman.
