Ex Cathedra (/ˌɛks kəˈθeɪdrə/ EKS-kə-THAY-drə) is a British choir and early music ensemble based in Birmingham in the West Midlands, England. It performs choral music spanning the 15th to 21st centuries, and regularly commissions new works.

Ex Cathedra was founded in Birmingham in 1969 by Jeffrey Skidmore, who is its artistic director and conductor. Originally conceived as a chamber choir, it now comprises a full choir of about 20 to 40 singers, the Ex Cathedra Consort made up of ten young professional singers who feature regularly as soloists, and a Baroque ensemble/orchestra.
