George Edward Wilson Cruttwell (5 December 1857 – 10 November 1933) was an English civil engineer. He worked with John Wolfe Barry and Henry Marc Brunel, was the resident engineer in charge of the construction, and then first superintending engineer, of Tower Bridge in London, and remained associated with Tower Bridge until his death in 1933. He became an internationally renowned bridge engineer while also working on docks, harbours, railways and other infrastructure.

Cruttwell was born on 5 December 1857 to Wilson Clement Cruttwell, a solicitor, and Georgiana Daniel, in Frome, Somerset. One of 11 children, his youngest sister was art historian and critic Maud Cruttwell. Like his brothers, he was educated at Clifton College from 1869 to 1874, then King's College London. After graduating, in October 1876 he was apprenticed to railway engineer Robert Pearson Brereton who was responsible for completing many of Isambard Kingdom Brunel's projects after his death in 1859.

Cruttwell spent a year in Brereton's office before being assigned to harbour, railway and dock works for the Neath Harbour Commissioners as assistant resident engineer under one of Brereton's engineers, William Bell.

Cruttwell was only with Brereton until 1878 (or 1879) when he joined the firm of Sir John Wolfe Barry and Henry Marc Brunel. He initially spent four years working in Barry's and Brunel's office. But aged 25 he was appointed resident engineer responsible for the construction of Blackfriars Railway Bridge, a role he held between 1883 and 1886.

In 1886, Barry offered Cruttwell the choice of either becoming his personal assistant or the resident engineer at Tower Bridge. Cruttwell chose Tower Bridge and it was in this role he achieved national prominence as the engineer in charge of its construction from its inception in 1886 to its opening on 30 June 1894. Appointed to that post aged 28, Cruttwell was credited alongside Wolfe Barry (the bridge's chief engineer) with the work on the Bridge having "proceeded entirely under Mr Barry and his able resident engineer Mr Cruttwell." In 1898, after working for Wolfe Barry and Brunel for 16 years, Cruttwell was nominated to become a member of the Institution of Mechanical Engineers; Brunel summarised Cruttwell's career to that year:

"[He was educated] at King's College, London (Applied Science Department) from 1874 to 1876... From 1878 to 1894, Cruttwell was employed continuously by Mr (later Sir) John Wolfe Barry and Mr Henry Marc Brunel initially in their office, then in sole charge as resident engineer at Blackfriars Railway Bridge from 1883 to 1886, and then at the Tower Bridge from 1886 to 1894."

Cruttwell would present two substantial papers to the Institution of Civil Engineers on the construction of Tower Bridge which form the basis of much of the current understanding of the engineering. On 28 March 1893 he presented a detailed paper on the foundations, while on 19 November 1896, he presented on the superstructure. The following month, in the usual discussion on papers previously presented, Cruttwell robustly defended the Tower Bridge from its engineering critics, noting in reply to one who suggested that the failure to make it a railway bridge would mean it would have to be pulled down that "As for the day coming when the bridge would have to be pulled down, he could only say it would be a very good thing for engineers, as it would give them some work to do."

After Tower Bridge was opened, the Corporation of London "secured the services of Mr E W Cruttwell who so very ably filled the post of resident engineer during the whole period of construction" as the engineer in charge of the now operational Tower Bridge, for which he received £500 per year. He retained this position until 1897 when the roles of engineer and bridge master were merged. Bridge House Estates also appointed him as engineer for Southwark and London bridges.
