Te Deum is a setting of the Latin Te Deum text, also known as the Ambrosian Hymn attributed to Saints Ambrose, Augustine, and Hilary, by Estonian-born composer Arvo Pärt, commissioned by the Westdeutscher Rundfunk in Cologne, Germany, in 1984.  Dedicated to the late Alfred Schlee of Universal Edition, the WDR Broadcast Choir premiered the Te Deum under the direction of conductor Dennis Russell Davies on January 19, 1985.  The Te Deum plays an important role in the services of many Christian denominations, including the Paraklesis (Moleben) of Thanksgiving in the Eastern Orthodox Church.  Because of the unusual instrumentation Pärt employs, his Te Deum is not suited for use within the Orthodox Church.

The piece is approximately thirty minutes long. The Estonian Philharmonic Chamber Choir (EPCC) is a professional choir based in Estonia.
