Albert Ernest Knight (8 October 1872 - 25 April 1946) was an English professional cricket player. He was born in Leicester and educated at Wyggeston Grammar School for Boys. He died in London.

From 1895 until 1912 he played for Leicestershire, and represented England in three matches of the 1903-04 Ashes series against Australia.

His most important contribution to the game (but one that is often omitted from accounts of his life) was a book, The Complete Cricketer, published in 1906. Sir Derek Birley, in his A Social History of English Cricket, described it as "a masterpiece of its kind, stuffed full of learned observations in weighty prose".
