The Edward Appleton Medal and Prize is awarded by the Institute of Physics for distinguished research in environmental, earth or atmospheric physics.

Originally named after Charles Chree,[1] the British physicist and former President of the Physical Society of London, it was renamed in 2008 to commemorate Edward Victor Appleton, winner of the Nobel Prize for proving the existence of the ionosphere.

[1] The prize was established in 1941 by Chree's sister, Jessie, after his death, and it was originally awarded biennially.

After the 2008 renaming the prize was awarded in even-dated years until 2016, then as and when required.

The cash prize part of the award has risen in value since its inception, reported at £150 in 1985[5] and £300 in 1987,[6] to its present-day value of £1000.
