Sir Henry Lynch, 1st Baronet (died 1635) was a knight and land agent.
Lynch was the son of Nicholas Lynch fitz Stephen (Mayor 1584–1585) and great-grandson of Mayor Arthur Lynch (died 1539). He was a land agent for Richard Burke, 4th Earl of Clanricarde; their surviving correspondence from c.1617 to c.1632 was published in 1996. He was a mentor to Patrick D'Arcy and Richard Martyn, later senior political figures of Confederate Ireland. He was stepfather to D'Arcy and married to an aunt of Martyn.
He was among the first of his family to become a lawyer, and several of his younger sons followed him into this profession, as did, under his influence, D'Arcy, Martyn, Geoffrey Browne and subsequent generations of The Tribes of Galway.
The baronetcy was created for Henry Lynch on 8 June 1622.
Lynch is said by some to have been knighted in 1627.
