George Augustus Chichester May PC, QC (1815 – 16 August 1892) was an Irish judge.
May was born in Belfast, the son of the Reverend Edward May and Elizabeth Sinclair.
He was educated at Shrewsbury School and Magdalene College, Cambridge, where he graduated B.A.
In 1877 he became Lord Chief Justice of the Queen's Bench for Ireland and on the passing of the Judicature Act became Chief Justice of the Queen's Bench Division of the Irish High Court.
According to F. Elrington Ball's work on the pre-1921 Irish judiciary, while May was a considerable scholar, he was not well regarded as a barrister and his appointment was greeted with some protest.
