London Oriana Choir is a choral group comprising around 120 singers, based in London, England. It was formed in 1973 by Leon Lovett, who acted as conductor and musical director. David Drummond became the choir's musical director in 1996, and Dominic Ellis-Peckham began his term as musical director in September 2013. The choir has developed a following through performances at London venues including the Royal Albert Hall, Barbican Centre, Royal Festival Hall and Queen Elizabeth Hall at Southbank, St Paul's Cathedral, St Martin-in-the-Fields and St James' Piccadilly. In 2016 the choir launched a five-year project 'five15' to promote the work of women composers with 15 new commissions from five composers, workshops and recordings. The five commissioned composers-in-residence were Cheryl Frances-Hoad (2016/17), Rebecca Dale (2017/18), Jessica Curry (2018/19), Anna Disley-Simpson (2019-2021), and Hannah Kendall (2021/22). Composer Cecilia McDowall accepted the role of Patron of the choir in 2021. The choir celebrated its 50th anniversary in the 2023/24 season, commissioning a new piece 'Here Hum The Bees' from Cecilia McDowall, which was premiered at a gala concert at St John's Smith Square in March 2024.
The choir tours regularly and since 2015 has performed in France, Portugal, Germany, Malta, Poland, and Italy.
