Nicholas de la Beche (died 1345), Seneschal of Gascony, was a 14th-century English noble.

During 1339, Beche married Margery Poynings, the widow of Edmund Bacon.

The young princesses Isabella and Joanna, daughters of King Edward III and Queen Philippa of Hainault were left in the care of Beche in 1340; however, upon the unexpected return of the king, the living conditions and guarding of the princesses were found to be inadequate and Beche was arrested.

Beche was sent in 1345 as one of the commissioners to treat the betrothal of the English princess Joanna with Peter of Castile, the eldest son of King Alfonso XI of Castile and Maria of Portugal.

Beche was employed in King Edward III's wars in Brittany and Gascony.
