Colin Milne (c.1743–1815) was a Scottish priest of the Church of England and botanist.
Born at Aberdeen about 1743, Milne was educated at Marischal College there under his uncle, Dr. Campbell, and later received the degree of LL.D. from the university. He moved to Edinburgh, and became tutor to Lord Algernon Percy. Taking Anglican orders, he made a reputation as a preacher.
Milne was appointed evening preacher to the City of London Lying-in Hospital, and lecturer to both the Old and the New Church at Deptford. Subsequently made rector of North Chapel, near Petworth in Sussex, he continued, however, to reside at Deptford where in 1783 he founded the Kent Dispensary, which became the Miller Hospital, Greenwich. He was a prominent promoter of the Royal Humane Society, and several times preached the anniversary sermon for the society.
Milne died at Deptford on 2 October 1815.
