Arthur William à Beckett (1844-January 14, 1909), English journalist and man of letters. He was a younger son of Gilbert Abbott à Beckett and brother of Gilbert Arthur à Beckett.

Beckett was on the staff of Punch from 1874 to 1902, and gave an account of his father and his own reminiscences in The A Becketts of Punch (1903).

A childhood friend (and distant relative) of W. S. Gilbert, Beckett briefly feuded with Gilbert in 1869, but the two patched up the friendship, and Gilbert even later collaborated on projects with Beckett's brother.

Beckett died in London.
