Homersham Cox (1821–1897) was an English lawyer and judge, mathematician and historian.
He was born at Newington, Surrey, the fourth son of Edward Treslove, and was educated at Tonbridge School. He entered Jesus College, Cambridge in 1839, graduating B.A. in 1844, and M.A. 1852. He was admitted to the Inner Temple in 1845, and was called to the Bar 1851.
Cox died on 10 March 1897, at Marl Field House, Tonbridge.
In The Institutions of the English Government (1863), Cox argued in terms of a constitutional "balance of powers", at variance with the contemporary theorists Walter Bagehot and A. V. Dicey. A History of the Reform Bills of 1866 and 1867 was acknowledged by the author as a partisan Liberal work. It was brought out in time for the 1868 United Kingdom General Election. He was a critic of the cross-party co-operation seen in passing the Reform Bill of 1867, arguing that democracy was being undermined.
Other works were:
- The British Commonwealth, Or, A Commentary on the Institutions and Principles of British Government (1854). In it Cox argued that the Norman Conquest led to attempt to break down the local Anglo-Saxon political institutions.
- Whig and Tory administrations during the last thirteen years (1868)
- Antient Parliamentary Elections: A history showing how parliaments were constituted and representatives of the people elected in antient times (1868)
