Henry Vaughan (1621 - April 28, 1695) was a Welsh Metaphysical poet and a doctor, the twin brother of the philosopher Thomas Vaughan.
Vaughan was born, and lived for most of his life, in the village of Llansanffraid, near Brecon, where he is buried. During the English Civil War, he was a Royalist sympathiser. He took his literary inspiration from his native environment, calling himself a "Silurist" in homage to the Silures, the Celtic tribe of south Wales which resisted the Roman Invasion of Britain. Vaughan's greatest verse appears in the collection Silex scintillans, first published in 1650.
