The battle of Buulo Mareer took place on 26 May 2023, when Al-Shabaab fighters stormed an African Union military camp manned by Ugandan forces in the town of Bulo Marer, Lower Shabelle, Somalia.

The attack remains the deadliest on ATMIS troops (successor to AMISOM) since their formation in April 2022 and is also Uganda's worst defeat in Somalia since its deployment in February 2007.
