Sir Herbert Lloyd, 1st Baronet (22 July 1720 – 19 August 1769) was a Welsh politician.

Lloyd was born in Llanddewibrefi and educated at Jesus College, Oxford. His father, Walter Lloyd of Voelallt, Cardiganshire, was attorney-general for south Wales and was succeeded by Herbert's elder brother, John Lloyd. Herbert Lloyd also trained as a lawyer, and was called to the bar by the Inner Temple in 1742. In 1761 he became MP for Cardigan Boroughs, and in 1763 he was created a baronet. His later years were marked by increasing debt, the loss of his parliamentary seat and poor health. He died en route to Bath; there is no foundation for the tradition that he committed suicide.^[1] Although he was married twice, he left no heir.
