James Forbes (4 April 1813 – August 1851) was a Scottish-Australian Presbyterian minister and educator. He founded the Melbourne Academy, later Scotch College.
James Forbes was the oldest of the ten children (only five surviving infancy) born to Peter and Margaret Forbes who farmed "New Braes" on the estate of Sir Arthur Forbes in the parish of Leochel-Cushnie about 40 km west of Aberdeen, Scotland. He was baptised on 4 April 1813, and was educated locally and at Aberdeen Grammar School.
He entered King's College, Aberdeen in 1826 and completed the Arts course in 1829 but, like the majority of students who regarded it as an expensive formality, he did not bother to graduate. The Church of Scotland's Presbytery of Garioch records show that he was enrolled in divinity for part of 1829/30, 1830/31 and as a regular student 1831/32. He must have had doubts about his fitness for the ministry for he accepted a teaching appointment at the Colchester Royal Grammar School in England between 1832 and 1835. Here he experienced an evangelical conversion as he heard the sermons given in the school assembly by the Church of England preachers. This brought him back to the divinity course at Aberdeen which he completed in 1837.
He was licensed as a preacher by the Presbytery of Garioch on 10 May 1837. Recruited for Australia through the influence of Rev John Dunmore Lang he was ordained with his friend William McIntyre by the Presbytery of Glasgow on 29 June 1837 for work in Australia.
Leaving Greenock on the 541 ton barque Portland on 24 July 1837, Forbes arrived in Sydney on 4 December 1837. The passengers included Dr Lang and a number of other ministers and teachers. Forbes rejected Lang's proposal that the new ministers join him in forming the Synod of New South Wales to rival the existing Presbytery of New South Wales, and duly became a member of the Presbytery. His appointment being for the District of Port Phillip, he arrived there by boat on 20 January 1838.
