John Atkinson Grimshaw(约翰·阿特金森·格里姆肖)，（1836年至1893年）英国画家，是唯美主义画派的代表人物。维多利亚时期最负盛名和影响力的画家之一。
John Atkinson Grimshaw (6 September 1836 – 13 October 1893) was a Victorian-era artist, a "remarkable and imaginative painter" known for his city night-scenes and landscapes.[2His early paintings were signed "JAG," "J. A. Grimshaw," or "John Atkinson Grimshaw," though he finally settled on "Atkinson Grimshaw."
John Atkinson Grimshaw was born 6 September 1836 in Leeds. In 1856 he married his cousin Frances Hubbard (1835–1917). In 1861, at the age of 24, to the dismay of his parents, he left his job as a clerk for the Great Northern Railway to become a painter. He first exhibited in 1862, mostly paintings of birds, fruit and blossom, under the patronage of the Leeds Philosophical and Literary Society. He became successful in the 1870s and rented a second home in Scarborough, which became a favourite subject.
Several of his children, Arthur Grimshaw (1864–1913), Louis H Grimshaw (1870–1944), Wilfred Grimshaw (1871–1937) and Elaine Grimshaw (1877–1970) became painters.
