Charles Mathew Gray (1853 – 11 June 1918) was a New Zealand Independent Member of Parliament for Christchurch North, and Mayor of Christchurch.

Charles Gray was born in Geelong, Victoria, in Australia and came to New Zealand in 1862.

Gray was elected to the Christchurch City Council in 1885. Mayoral elections were held on 26 November 1890. The two candidates were the incumbent, Samuel Manning, and Gray, who received 492 and 665 votes, respectively. Gray was thus elected as the 17th mayor of Christchurch^[1] and was installed on 17 December 1890.^[2] He was mayor until the end of 1891. On 18 April 1904, he succeeded Henry Wigram as mayor, when he was declared elected unopposed.^[3] He served for one year, and his chief aims were beautifying the city, drainage, sanitation, lighting and high pressure water supply.

Charles Gray represented the Christchurch North electorate in the New Zealand House of Representatives from the 1905 election to 1908.

Gray defeated Tommy Taylor in the 1905 contest for Christchurch North.

Gray made it clear during the election campaign that he was an independent Liberal who would go to the House unfettered by party obligations. He declared that he was not a 'party man'.^[4]

Gray died in Christchurch on 11 June 1918.
