Sir Thomas Dagworth (1276 – 20 July 1350) was an English knight and soldier, who led the joint English-Breton armies in Brittany during the Hundred Years' War.

Hundred Years War Breton War of Succession In 1346 he led a small English force in Brittany in support of John de Montfort's claim on the dukedom. De Montfort was backed by the English throne, whereas his rival, Charles of Blois was backed by the French. On 9 June, Dagworth's force was attacked by Charles' much larger army in the Battle of Saint-Pol-de-Léon. Though almost surrounded, the longbowmen won the day for the Anglo-Breton Forces.

The next year, on 20 June, he claimed an even more famous victory at the Battle of La Roche-Derrien, where he captured Charles of Blois.

He was summoned to the Parliament of England in 1347 as Baron Dagworth.

He was killed in an ambush on 20 July 1350, near Auray, a few miles west of Vannes, by a Franco-Breton force under Raoul de Caours.
