Alfred Bryan (born as Charles Grineau) was a popular English illustrator, best known for his many contributions to the London-based weekly theatrical review Entr'acte.

He was born as Charles Grineau in Marylebone in London in 1852, the eldest of five children of Elizabeth née Newman (1840-1804) and William Henry Grineau (1829-1902), a baker. Bryan's first professional sketches were published in The Hornsey Hornet. He also produced sketches for The London Figaro. Bryan worked for the Illustrated Sporting and Dramatic News for most of his career and was also published in periodicals such as Judy magazine. Walter Sickert, a contemporary art critic, described him as "the complete, trained draughtsman", praising his illustrations as "[...]unfaltering in their mastery of line, their perfect style, their elegance and wit."

Bryan died in May 1899 and was buried in New Southgate Cemetery, in Barnet, North London. He left an estate valued at £2,309 9s 9d.

His son was Charles William Grineau (1883–1957), an artist known for his paintings of motorcars under the pseudonyms Bryan de Grineau and John Bryan.
