Fort Pitt was a fort in what is now Allegheny County, Pennsylvania. It was named Fort Pitt for William Pitt the Elder after the British under General John Forbes captured the French-held Fort Duquesne in 1758. They destroyed the old fort and rebuilt it with a moat.
For a brief while in the 1770s the fort was called Fort Dunmore, in honour of Virginia's Governor Lord Dunmore.
