James Farrer (8 May 1812 – 13 June 1879) was a Conservative Party politician in England who was elected three times as Member of Parliament (MP) for South Durham. He unsuccessfully contested the 1841 general election, but was elected unopposed in 1847 after John Bowes stepped down. He was re-elected unopposed in 1852, but in 1857 he lost his seat to the Liberal candidate, Henry Pease. When the Liberal Lord Harry George Vane stepped down at the 1859 general election, Farrer was again elected unopposed. He retired from politics at the 1865 general election.
