The Old Cannon Brewery is a brewpub in Bury St Edmunds, Suffolk, UK.

This Victorian property was originally home to the Cannon Brewery, which closed during World War I.

It was later home to a Greene King pub called The St Edmunds Head, which closed in the early 1990s.

The St Edmundsbury Record Office shows Pat and Liz Spillane purchased the property from Greene King in 1994, renovated the buildings, and reopened as The Old Cannon Brewery in December 1999.

The names of many of the beers maintain a British nautical theme.
