Burnham-on-Sea is a town in Somerset, England, at the mouth of the River Parrett. It suffered a major flood in 1607, and remained a small village until the late eighteenth century.

The town is notable for its collection of lighthouses, including the Round Tower lighthouse of 1829, the Pillar Lighthouse and the Lighthouse on legs. Burnham is now a popular seaside resort, and is home to the shortest pier in Britain.

A number of marble carvings from the former chappel at the Palace of Whitehall can be seen in the local church of Saint Andrew, to where they were moved in 1820 after having originally been removed to Westminster Abbey in 1706.

Main School in town King Alfreds Community College.
