John Evershed (26 February 1864 – 17 November 1956) was an English astronomer. He was the first to observe radial motions in sunspots, a phenomenon known as the Evershed effect.

Evershed was born in Gomshall, Surrey, on February 26, 1864. He made the discovery which bears his name in 1909, and in 1918 was awarded the Gold Medal of the Royal Astronomical Society. He died in Ewhurst, Surrey on November 17, 1956.

The crater Evershed on the Moon is named in his honor.
