Jane Porter (1776-1850) was an English novelist, the sister of Anna Maria Porter.

Jane, though the elder by four years, did not publish until 1803, when her first novel, Thaddeus of Warsaw, appeared. The Scottish Chiefs followed in 1810. Both of these works, especially the latter, were very popular, the Chiefs being translated into German and Russian. She probably had greater talent than her sister, but like Anna Maria, had many limitations. A romance, Sir Edward Seaward's Diary (1831), purporting to be a record of actual circumstances, and edited by Jane, is generally believed to have been written by a brother, Dr. William Ogilvie Porter.
