Mary Tighe (née Blackford) (1772 - 1810), was an Anglo-Irish poet.

She was born in Dublin to Theodosia Tighe, a Methodist leader, and William Blachford (d.1773?), a Church of Ireland clergyman and librarian. She had a strict religious upbringing, and when she was twenty-one she married Henry Tighe (1768–1836), her first cousin and a member of the Parliament of Ireland for Inistioge, County Kilkenny. The marriage is said to have been unhappy, though little is known.

The couple moved to London and Tighe became acquainted with Thomas Moore and others interested in literature. Although she had written since girlhood, she published nothing until Psyche (1805), a six-canto allegorical poem in Spenserian stanzas.

Having suffered from tuberculosis for some years, Tighe spent the last months of her life an invalid and died in 1810. Her diary was destroyed, though a cousin copied out excerpts.

The year following her death a new edition of Psyche was released, along with some previously unpublished poems; it was this edition that established her literary reputation. John Keats was one of her admirers and paid tribute to her in his poem, "To Some Ladies." Pam Perkins writes that "[d]espite the bleakness of many of the short poems in the 1811 volume, in much of the nineteenth-century writing on Tighe there is a tendency to turn her into an exemplar of patiently (and picturesquely) long-suffering femininity, a tendency exemplified most famously in Felicia Hemans's tribute to her, 'The Grave of a Poetess.'"
