James Alexander Haldane (1768–1851) was a Scottish independent church leader.
In about 1796 he became acquainted with the celebrated evangelical, Charles Simeon of Cambridge, in whose company he toured Scotland, distributing tracts and trying to awaken others to an interest in religious subjects. In May 1797 he preached his first sermon, at Gilmerton near Edinburgh, with encouraging success. In the same year he established a non-sectarian organization for tract distribution and lay preaching called the Society for the Propagation of the Gospel at Home. During the next few years he made repeated missionary journeys, preaching wherever he could obtain hearers, and generally in the open air.
