The French Tower is a tower at the top of Castle Street in Waterford, Munster, Ireland. It is one of the six surviving towers of the city walls of Waterford. The tower most likely dates from the 13th or 14th century. The origin of the name is uncertain, but it may well be connected with the large French community which lived in Waterford from the period following the Battle of the Boyne in 1690. Many of these people were of Huguenot origin, and their descendants still live in Waterford to this day. The tower is located at the point where the city wall makes a sharp turn, coming up from Manor Street, past Double Tower, and then continuing in a northerly direction to Newgate Street along Browns Lane.
