Evert Ernst Erland Olof Lundquist (17 July 1904, Stockholm – 4 November 1994, Stockholm) was a Swedish painter and graphic artist. He was born in Stockholm, the son of a railway official, Ernst Lundquist. He trained as an artist at Carl Wilhelmson's painting school in Stockholm, at the Académie Julien in Paris and at the Royal Swedish Academy of Arts (1925-1931), where Olle Hjortzberg was a teacher.
His first exhibition was at the Konstnärshuset in Stockholm in 1934, but he became popular only in the 1940s. He lived and worked in Saltsjö-Duvnäs, on the outskirts of Stockholm, and from 1953 at Drottningholm. He was awarded the Prince Eugen Medal for painting in 1961. He worked as a teacher at the Gerlesborgs art school and as a professor at the Academy of Arts from 1960 to 1970.
He died in Stockholm in 1994. From his marriage to Ebba Reutercrona he had two children, Hübner "Hymme" Olof Alexis Lundqvist and Emanuel "Manne" Lundquist. Hübner disappeared without a trace on the way to Gerlesborg in 1965.
