Rowland Mason Ordish (11 April 1824 – 1886)[1] was an English engineer.
He is most noted for his design of the Winter Garden, Dublin (1865),[2] for his detailed work on the single-span roof of London's St Pancras railway station, undertaken with William Henry Barlow (1868)[3] and the Albert Bridge, a crossing of the River Thames in London, completed in 1873.
