Bannfoot (also historically known as Charlestown) marks the point where the Upper Bann meets Lough Neagh in County Armagh.

The entrance from the lough is notably shallow and lacks navigation markers, meaning entry to the river should not be attempted without local knowledge.

A short distance upstream stand the jetties of the former Bann Ferry, which no longer operates but can still be used for a brief stop.

From there, the villages of Bannfoot on the east bank and Columbkille on the west bank are reachable on foot in around ten minutes.

The Upper Bann, though officially abandoned as a navigation in 1954, remains navigable between this point and Whitecoat Point near Portadown, and is regarded as one of the most popular coarse fishing stretches in Europe.
