The Leominster by-election was a by-election held on 15-16 February 1876 for the British House of Commons constituency of Leominster in Herefordshire.
The by-election was caused by the resignation on 8 February 1875 of the serving Conservative Party MP, Richard Arkwright. After a close-fought campaign, the result was a gain for the Liberal candidate, Thomas Blake, with a majority of 85 over the Conservative, Charles Spencer Bateman Hanbury Kincaid-Lennox, brother of Lord Bateman. This came as something of a surprise as no Liberal had been elected to the constituency for the previous 25 years.
