Sir Charles John Johnston (11 October 1845 – 13 June 1918) was a New Zealand politician.

He subsequently joined the volunteers and when the Wellington Brigade formed was appointed to the rank of captain.

[6] He was appointed from 22 January 1891 as one of seven new members (including Harry Atkinson himself) appointed to the council by the outgoing fourth Atkinson Ministry; a move regarded by Liberals as a stacking of the upper house against the new government.

Another four of his sons also served in the war - Guy, Charles, Harold, and Ian Johnston.

Zoë was widowed on the death of her husband William Fitzgerald Levin from injuries suffered at Gallipoli, while Doris married Hon.
