The Haffner Orchestra is an orchestra based in Lancaster, England. Comprising amateur players and local professionals, the orchestra usually gives three concerts a year in November, February and June.^[1] These are held in the University of Lancaster's Great Hall and Lancaster Town Hall's Ashton Hall,^[2] often drawing audiences of around 500. In addition, workshops, masterclasses, open rehearsals and community events are part of the orchestra’s programme.

The orchestra was formed in 1976, starting as a chamber orchestra and expanding to a full symphony orchestra. It took its name from Mozart's Haffner Symphony, which in turn was named after one of Mozart's patrons, Sigmund Haffner der Elder [de].

It is a registered charity, number 509571, and its President is the cellist Raphael Wallfisch.
