Norman Garstin (August 28, 1847 - June 22, 1926) was an Irish artist associated with the Newlyn School of painters.
He was born in Cahirconlish, Co. Limerick, Ireland, and was involved in various professions such as journalism and gold mining in South Africa. In 1885 he befriended members of the Newlyn School and settled there a year later, moving to nearby Penzance in 1890.
His work consisted primarily of small oil panels in the plein air style, something he had picked up from the French Impressionists such as Edouard Manet and Edgar Degas. He was also fascinated by Japanese calligraphy and admired the work of the American painter James McNeill Whistler.
His most famous painting was The Rain it Raineth Every Day (1889; Penzance, Penlee House Mus. & A.G.). His daughter, Alethea Garstin, was also a painter. They lived for many years in Wellington Terrace. In 1960 the borough council decided to demolish their art studio where much of their painting had been done and as a result valuable work was lost. Alethea then moved from the only home she had known at the age of 66 to a new studio adjacent to Patrick Heron's house near Zennor.
