Henri Marc Brunel (1842-1903) was the second son of the celebrated English engineer Isambard Kingdom Brunel, and followed his father's footsteps in becoming a civil engineer.

He is noted for a partnership from 1878 with Sir John Wolfe-Barry, with whom he designed the Blackfriars Railway Bridge over the River Thames in central London. Their other works included the docks at Barry in south Wales and the Creagan Bridge, a railway bridge over the narrows of Loch Creran at Dallachoilish (near Oban) in Scotland (jointly credited to Wolfe-Barry, H.M. Brunel and E.M. Crutwell).

Among the pupils articled to Brunel and Wolfe-Barry was Sir Alexander Gibb in 1895.
