Saaremaa Municipality, also known as Saaremaa Rural Municipality (Estonian: Saaremaa vald), is a municipality in Saare County in western Estonia. It is the largest municipality in Estonia by land area. The administrative centre of the municipality is its only town Kuressaare.
It is one of three parishes comprising the county, along with Muhu and Ruhnu Parish.
