Chester Shot Tower, also known as Boughton Shot Tower, is a grade-II*-listed shot tower located at SJ413667 in the Boughton district of Chester, England. The tower stands beside the Shropshire Union Canal and forms part of the disused Chester Leadworks. Built by Walkers, Parker & Co. in 1799, the tower is the oldest of three remaining shot towers in the UK, and probably the oldest such structure still standing in the world.
