A crown steeple, or crown spire, is a traditional form of church steeple in which curved stone flying buttresses form the open shape of a rounded crown. Crown spires first appeared in the Late Gothic church architecture in England and Scotland during the Late Middle Ages, continued to be built through the 17th century and reappeared in the late 18th century as part of the Gothic Revival.

The crown steeple on Newcastle Cathedral was erected in 1448.

The crown spire of St Giles' Cathedral, Edinburgh was erected in 1495, and rebuilt by John Mylne in 1648.

Another medieval crown steeple was built on the Chapel of King's College, Aberdeen (1500–1509), although this too was rebuilt in the 17th century, after the original blew down.

The crown steeple of the Glasgow Tolbooth, in Glasgow's Merchant City, was built in 1626–1634 by John Boyd, and at the time was the only such steeple in western Scotland.

In 1698, Sir Christopher Wren added a tower with a crown steeple to St Dunstan-in-the-East, London.

Crown steeples were often incorporated into Gothic Revival churches. An octagonal bell tower with crown spire was added to St Giles' Church in Pontefract in 1790. The open spire of Faversham Parish Church, Kent was built in 1797, and a crown steeple was added to Tillington Parish Church, Sussex, in 1807.

A secular example tops the Wallace Monument, near Stirling, erected in 1869 to a design by the architect John Thomas Rochead.
