Sir Thomas de Hungerford (died 3 December 1397) of Farleigh Castle in Wiltshire, was the first person to be recorded in the rolls of the Parliament of England as holding the office of Speaker of the House of Commons of England, although that office had existed before his tenure.
Hungerford was the son of Walter de Hungerford of Heytesbury, Wiltshire, thrice Member of Parliament for Wiltshire, in 1331/2, 1333/4 and 1336. His mother was Elizabeth FitzJohn, daughter and heiress of Sir Adam FitzJohn of Cherhill in Wiltshire. The Hungerford family had been seated in Wiltshire since at least the twelfth century.
Thomas's uncle was Robert Hungerford (d.1355), Member of Parliament for Wiltshire in 1316 and a commissioner to inquire into the possessions of the Despensers after their attainder in 1328, and gave much land to the hospital at Calne in memory of his first wife, Joan, to the church of Hungerford, Wiltshire, and to other religious foundations. He was buried in 1355 in Hungerford Church, where an elaborate monument long existed above his grave. An inscription to his memory is still extant in the church. His second wife was Geva, widow of Adam de Stokke, but he left no issue.
Hungerford was Sheriff of Wiltshire from 1355 to 1360 and served several times as a Member of Parliament for Wiltshire: in April 1357, in 1360, 1362, January 1376/7, twice in 1380, in 1383, 1384, 1386, January 1389/90, and in January 1392/3. He served as Member of Parliament for Somerset in 1378, 1382, 1388, and 1390. He was returned for both constituencies in 1384 and January 1389/90. He was knighted in February 1375. He was closely associated with John of Gaunt and acted for some time as steward of Gaunt's household.
