Lieutenant General Sir John Guise Cowley, GC, KBE, CB (20 August 1905 – 7 January 1993) was a British Army officer and George Cross recipient who reached high rank in the 1950s.

Returning to England as a baby, his early years were spent in a Dorset village, where his father was the rector.

Here he was awarded the Albert Medal, subsequently exchanged for the George Cross, for his actions in rescuing survivors from the ruins of a collapsed hospital during the Quetta earthquake of May 1935.

At first, the men were too few in number to tear off the roofs, so they raised them up for short periods whilst Lieutenant Cowley crawled under them and dragged out survivors from their beds.

[16] In retirement, Cowley served as a director of a number of companies; as president of the New Forest Preservation Society and as chairman of the governors of Wellington College.
