Sir John Malcolm Inglis DL (14 December 1837 – 24 April 1902) was a Scottish Liberal Unionist politician in Ireland and a prominent businessman.
The greater part of his career was passed in Dublin, where he was head of the firm Heiton and Co, iron and coal merchants and shipowners.
He was for many years a member of the Port and Docks Board, and took an active part in the industrial development of Dublin.
He was liberal, yet a prominent supporter of the union between Ireland and the rest of the United Kingdom.
The same source states that he was originally offered a baronetcy, but declined this hereditary title as he did not find his eldest son worthy of it, and instead accepted a knighthood.
