Alexander Balloch Grosart (18 June 1827 – 16 March 1899) was a Scottish clergyman and literary editor. He is chiefly remembered for reprinting much rare Elizabethan literature, a work which he undertook because of his interest in Puritan theology.
The son of a building contractor, he was born at Stirling and educated at the University of Edinburgh. In 1856 he became a minister of the United Presbyterian Church of Scotland at Kinross, serving the congregation known as First United Presbyterian Church. In 1865 he went to Liverpool, and three years later to Blackburn.
He resigned from the ministry in 1892, and died at Dublin.
Among the first writers whose works he edited were the Puritan writers, Richard Sibbes, Thomas Brooks and Herbert Palmer. Editions of Michael Bruce's Poems (1865) and Richard Gilpin's Demonologia sacra (1867) followed. In 1868 he brought out a bibliography of the writings of Richard Baxter, and from that year until 1876 he was occupied in reproducing for private subscribers the “Fuller Worthies Library,” a series of thirty-nine volumes which included the works of Thomas Fuller, Sir John Davies, Fulke Greville, Edward de Vere, Henry Vaughan, Andrew Marvell, George Herbert, Richard Crashaw, John Donne and Sir Philip Sidney. The last four volumes of the series were devoted to the works of many little known and otherwise inaccessible authors. He also wrote a biography of the Scottish poet, Robert Fergusson (Edinburgh: Oliphant, Anderson and Ferrier, 1898) in the “Famous Scots Series”.
