The King's Gallery, previously known as the Queen's Gallery, is a public art gallery at Buckingham Palace, the official residence of the British monarch, in London. First opened to the public in the reign of Elizabeth II in 1962, it exhibits works of art from the Royal Collection on a rotating basis. Enlarged in the early 21st century, the gallery has its own separate public access entrance built in a "new" classical style and typically displays about 450 works, mainly paintings and drawings.

The gallery forms the most protruding south wing of the Palace. It is on the site of the palace chapel bombed during the Second World War. The purpose-built gallery opened in 1962; in the next 37 years it received five million visitors, until its closure in 1999 for refurbishment and expansion. The work was commissioned from architect John Simpson. On 21 May 2002, the gallery was reopened by Elizabeth II to coincide with her Golden Jubilee. The new work included a Doric entrance portico and new rooms, more than tripling the space available. It is open to the public for most of the year.
