Reginald West, 6th Baron De La Warr

Reginald West, 6th Baron De La Warr and 3rd Baron West (5 or 7 September 1395 – 27 August 1450) was an English nobleman.

He was the second son of Thomas West, 1st Baron West (d. 19 April 1405) and Joan La Warre (d. 24 April 1404), widow of Ralph de Wilington (d. 16 August 1382) of Sandhurst, Gloucestershire, and daughter of Roger La Warr, 3rd Baron De La Warr (d. 27 August 1370), by his second wife, Eleanor Mowbray, daughter of John de Mowbray, 3rd Baron Mowbray. He had an elder brother, Thomas West, 2nd Baron West, a younger brother, John, and a sister Joan, who married firstly Richard Delabere and secondly William Catesby. He inherited the title of Baron West when his brother Thomas West, 2nd Baron West, was accidentally killed at sea on 29 or 30 September 1416, and the title Baron De La Warr in 1427 at the death of his uncle, Thomas la Warr, 5th Baron De La Warr (d. 7 May 1427).

West was knighted at some time before 1416, and on 22 November of that year had livery of the lands inherited from his brother, Thomas West, 2nd Baron West.

During the wars in France West was captain of the castle of Saint Lo in the Cotentin in Normandy in March 1418 and in April 1421, and captain of the fort of La Motte on 5 December 1419. On 21 June 1427 he had livery of the lands to which he was entitled as heir general of his uncle, Thomas la Warr, 5th Baron De La Warr.

West was summoned to Parliament from 15 July 1427 to 3 August 1429 as Reginaldo la Warre chivaler, and from 25 February 1432 to 23 September 1439 as Reginaldo West chivaler. In October 1427 he petitioned the King and Council 'that he might sit in Parliament with the precedence held by his ancestors, Lords la Warre, who had continually attended Parliament since 27 Edward I'.
