HMS Foylebank was a Royal Navy anti-aircraft ship active during the early part of the Second World War.

Foylebank was launched on 12 June 1930 as the 5,500-gross register ton motor merchant ship MV Foylebank for the Bank Line (Andrew Weir Shipping) and requisitioned by the Royal Navy when the Second World War broke out in September 1939.

These were originally thought to be Allied aircraft returning to base but they turned out to be 26 Luftwaffe Junkers Ju 87 Stuka dive bombers.

These aircraft had the objective of disabling Foylebank, which the Germans saw as a threat to their plans to destroy the United Kingdom's coastal shipping.

During an eight-minute attack, Foylebank shot down two aircraft, but an estimated 22 bombs hit the ship and she listed to port, shrouded in smoke, with 176 out of a total crew of 298 killed and many more wounded.. She sank on 5 July 1940.
