James was the son of Thomas Martineau, a manufacturer and wine merchant of Huguenot descent, and Elizabeth Rankin, and brother of Harriet Martineau.
After four years at the Norwich grammar school, two as pupil of Dr. Lant Carpenter in Bristol, and a short experience in the shops of a mechanical engineer in Derby, Martineau became a divinity student at Manchester College, York.
His first ministry was at Eustace Street Chapel, Dublin (1828–32), as assistant to his cousin, Reverend Philip Taylor.
From 1832–57, he was in Liverpool as minister of the congregation meeting in Paradise Street Chapel, and from 1849 in the new Hope Street Church.
In 1840 he was appointed professor of Mental and Moral Philosophy and Political Economy at Manchester New College, and in 1857 followed the college to London, becoming its Principal in 1869, and resigning in 1885.
On settling in London, he became minister of Little Portland Street Chapel, first in conjunction with Reverend J. J. Tayler, and afterward alone until his resignation in 1872. Oxford University awarded Martineau the degree of DCL in 1888.
