HMS Glasgow was a 20-gun sixth-rate post ship of the Royal Navy. She was launched in 1757 and took part in the American Revolutionary War. She is most famous for her encounter with the maiden voyage of the Continental Navy off Block Island on 6 April 1776. In that action, Glasgow engaged a squadron of 6 ships of the Continental Navy, managing to escape intact. She later chased two large Continental frigates in the Caribbean before she was accidentally burned in Montego Bay, Jamaica in 1779.
