Brian Frank Martin (2 November 1936 – 24 April 2023) was the fourth Chief Justice of the Supreme Court of the Northern Territory.
In pursuit of establishing a country law practice, he moved to Alice Springs in 1963 and, along with Ian Barker, was one of only two solicitors in the town at that time.
He was an inaugural member of the Northern Territory Law Society when it was formed in 1968 and was the Alice Springs representative from 1970 to 1977 and its Vice-President from 1972 - 1973.
Chief Justice Martin was appointed Northern Territory Solicitor-General and Secretary of the Department of Law in 1981 and relocated to Darwin.
He resigned as Secretary of the Department of Law on 3 May 1986 but stayed on as Solicitor-General until he was appointed a Judge of the Supreme Court of the Northern Territory on 30 September 1987.
