Autocode is a class of simple high-level programming languages devised for a series of machines at the Universities of Manchester and Cambridge. An early version was developed for the Ferranti Mercury, which was developed in the 1950s in conjunction with Manchester.

The version for the EDSAC 2 was devised by D F Hartley of University of Cambridge Mathematical Laboratory in 1961. It was Algol-like in structure and was optimised for use by scientists and engineers. Developments of it ran on the successor Titan (the prototype Atlas 2 computer), and a similar language was developed for the University of Manchester Atlas 1 machine (see Atlas Autocode)
