The Horsham by-election of 1876 was held on 29 February 1876. The byelection was fought due to the previous by-election being declared void. This had resulted in the election of the Liberal MP Robert Henry Hurst (junior). The Conservative candidate, Sir Hardinge Gifford, had been appointed as Solicitor General the year before, although he had not yet managed to get a seat in the Commons. It was won by the Liberal candidate James Clifton Brown.
