Lieutenant-Colonel William Brocklehurst Brocklehurst (18 May 1851 – 27 June 1929) was a businessman and Liberal Party politician from Macclesfield in Cheshire. He sat in the House of Commons from 1906 to 1918.

The son of William Coare Brocklehurst MP, he was educated at Cheltenham College and at Magdalen College, Oxford.
