Adam Lillie (1803-1869) was a Congregational minister and theologian. He was born in Scotland and studied at Glasgow University and the Theological Academy at Gosport. He was sent by the London Missionary Society (Congregational) to India in 1826, but poor health forced his return the following year. He was called to preach in Upper Canada in 1834, and appointed to teach at the new Congregational Theological Institute in 1839. He died suddenly in 1869.
