Rear Admiral Thomas Totty (1746 – 2 June 1802) was a Welsh naval officer of the Napoleonic Wars.

His father was an ironmonger and mine owner and had 21 other children – Thomas was one of 18 who survived infancy (another was his youngest brother Hugh, chaplain to George IV, who died aged 101).

HMS Alfred was stationed in the West Indies and with her Totty landed troops at St Lucia and Puerto Rico and in February 1798 captured three French ships.

However, the Invincible ran aground off Yarmouth and sank, with more than 400 men lost, though Totty and those of his officers who survived were found not guilty of negligence.

[1]Totty was appointed commander of the Leeward Islands Station on 17 November 1801 and set sail for there the following month.
