Elizabeth "Ella" Trefusis (16 January 1762 – 8 August 1808) was a Cornish poet of the Romantic period.

Her brother was Robert Trefusis, 17th Baron Clinton.

[1][2][3][4] Early in life, she wrote two novels, Claribell and Eudora, as well as a pastoral romance, The Cousins.

The poems are largely romantic and many the champion women wronged by men.

[2] William Beloe wrote extensively about Trefusis in his controversial memoir The Sexagenarian (1817), but his accuracy has been questioned.
