Harriet Evans Martin (died 1846) was an Anglo-Irish novelist.
George Evans, 4th Baron Carbery may have been a paternal relative, as she dedicated one of her books to him.
In May 1794 she remarried to Richard Martin MP (1754–1834), by whom she had three daughters and a son.
One of her children, Harriet Letitia Martin, would herself become a noted writer.
Martin established her reputation with the publication of her Remarks in 1802, a well-regarded critical study on the performances of stage actor John Philip Kemble (1757–1823).
