The United Secession Church (or properly the United Associate Synod of the Secession Church) was a Scottish Presbyterian denomination which existed between 1820 and 1847.

The First Secession from the established Church of Scotland had been in 1732, and the resultant "Associate Presbytery" grew to include 45 congregations. A series of disputes, in 1747 over the burgesses oath, and in the late 18th century over the Westminster confession, led to further splits. In 1820 two of the resulting groups, the New Licht Burghers and the New Licht Anti-Burghers, united to form the United Secession Church. The denomination existed until 1847 when it merged with the Presbytery of Relief to form the United Presbyterian Church.
