Ei-Q (28 April, 1911–10 March, 1960) was a Japanese artist who worked in a variety of media, including photography and engraving.

He was influenced by the Surrealist aesthetic and also published essays promoting photography as an art form independent of painting. This did not imply a rejection of painting, and he worked toward what in 1935 he termed photo-dessins, a fusion of photograms and paintings.
