Samuel Hughes (c.1816 - 31 October 1870) was a civil engineer and local politician.
The son of John Hughes, an engineer who had been involved in the development of many major canal and railway projects.
He worked with his father on the Holyhead Road before coming to London in the 1930s initially working on the construction of the London and Croydon Railway, later being involved in surveying and estimating work for many of the other railways in the capital.
After a spell working in South Wales and Gloucestershire on mining and bridge projects, Hughes returned to London in the early 1840s to work for the Tithe Commission. He settled in Westminster, and in the 1850s became known for his expertise on gas and water engineering.
He died at his residence and business premises at 14 Park Street, Westminster in 1870, aged 54.
