Ex Cathedra 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.

Each year, the choir presents a season of eight diverse programmes in a variety of venues in and around Birmingham and London. It has also participated in concert series and festivals across the UK and in Europe, including the BBC Proms, Brighton Early Music Festival, Kilkenny Festival, Lichfield Festival, Lufthansa Festival of Baroque Music, Spitalfields Festival, Three Choirs Festival and York Early Music Festival. In 2008 it was invited to the Newbury Spring Festival, St. David's Cathedral Festival, Chelsea Festival and Chichester Festivities. The choir has also appeared at festivals in Belgium, Finland, France, Germany, Israel, Italy and Spain. The ensemble collaborates regularly with other Birmingham-based arts organizations, including Birmingham Royal Ballet and the City of Birmingham Symphony Orchestra. It became an Associate Artist at the Birmingham Town Hall in 2007.

In 2009 Ex Cathedra was due to celebrate its 40th anniversary with a programme, XL Anniversary, that included a performance of Mendelssohn's Elijah on 18 October 2008, and to feature Elgar's The Dream of Gerontius in November 2009 and commissions from James MacMillan and Fyfe Hutchins. The choir also planned to make recordings of John Joubert's oratorio Wings of Faith, and pieces from its annual Christmas Music by Candlelight concerts.

Ex Cathedra is a British drama film written and directed by Liam Andrew Wright and production company Banter Media. It was Wright's directorial debut. The film's narrative centers on an original story combining religion, drugs, love and hope. It was an independently financed film, funded entirely by the films young producers and followed the model set by 2004 film Primer.
