Henry Glapthorne (baptised, 28 July 1610 – c. 1643) was an English dramatist and poet, baptized in Cambridgeshire, the son of Thomas Glapthorne and Faith née Hatcliff. His father was a bailiff of Lady Hatton, the wife of Sir Edward Coke. Before turning 14, Henry Glapthorne had matriculated as a pensioner at Corpus Christi College, Cambridge, but there is no record of him ever taking a degree. From then until he emerges as a playwright in the mid-1630s, little is known of him. There is evidence that he may have been employed as a groom-porter in a nobleman's household for some of that time – a later document refers to him as "Glapthorne the Porter" – but there is nothing conclusive.
