Everard Richard Calthrop (3 March 1857 – 30 March 1927) was a British railway engineer and inventor. Calthrop was a notable promoter and builder of narrow gauge railways, especially of 2 ft 6 in (762 mm) narrow gauge, and was especially prominent in India. His most notable achievement was the Barsi Light Railway; however he is best known in his home country for the Leek and Manifold Valley Light Railway. Calthrop has been described as a "railway genius". Later in life he took an interest in aviation, patenting some early designs for parachutes.
