Christ Church (Latin: Ædes Christi, the temple or house, ædes, of Christ, and thus sometimes known as "The House") is a constituent college of the University of Oxford in England. Founded in 1546 by King Henry VIII, the college is uniquely a joint foundation of the university and the cathedral of the Oxford diocese, Christ Church Cathedral, which also serves as the college chapel and whose dean is ex officio the college head.

As of 2022, the college had 661 students. Its grounds contain a number of architecturally significant buildings including Tom Tower (designed by Sir Christopher Wren), Tom Quad (the largest quadrangle in Oxford), and the Great Dining Hall, which was the seat of the parliament assembled by King Charles I during the English Civil War. The buildings have inspired replicas throughout the world in addition to being featured in films such as Harry Potter and The Golden Compass, helping Christ Church become the most popular Oxford college for tourists with almost half a million visitors annually.

The college's alumni include 13 British prime ministers (the highest number of any Oxbridge college), as well as former prime ministers of Pakistan and Sri Lanka. Other notable alumni include King Edward VII, King William II of the Netherlands, William Penn, writers Lewis Carroll (author of Alice in Wonderland) and W. H. Auden, philosopher John Locke, and scientist Robert Hooke. Two Nobel laureates, Martin Ryle and John Gurdon, studied at Christ Church. Albert Einstein is also associated with the college. The college has several cities and places named after it.
