Allen Overy Shearman Sterling LLP (commonly A&O Shearman) is a multinational law firm.

The merger terms were announced on 21 May 2023 and approved on 13 October 2023 by more than 99% of partners from both firms. The merger was completed on 1 May 2024, making it the fourth-largest firm in the world.

In April 2025, A&O Shearman in the United States agreed to provide $125m of pro bono work for causes supported by President Donald Trump in response to threatened presidential executive orders.
