Sir Humphrey Lynde (1579–1636) was an English lay Puritan controversialist and politician who sat in the House of Commons in 1626.
He was knighted by James I (29 October 1613), made a justice of the peace, and represented Brecknock in parliament February–June 1626 after Sir Walter Pye chose to sit instead for Herefordshire.
A report of the debate, The Romish Fisher Caught, 1624, was published by Featley, at the command of Archbishop George Abbot.
In 1623 Lynde published An Account of Bertram the Priest, with Observations concerning the Censures upon his Tract, "De Corpore et Sanguine Christi".
Lynde dedicated his work to Sir Walter Pye, and a copy was sent to James Ussher by Archbishop Abbot's chaplains Thomas Good and Daniel Featley).
Lynde also supported a collection made by Thomas James of passages from Protestant writers 'pruned away by the Romish knife.'
