Joel Jalmari Ruokokoski, known as Jali (1886-1936) was a Finnish Expressionist painter. Although most of his works were landscapes and still-lifes, he is probably best known for a series of portraits (including numerous self-portraits) painted mostly during the 1910s. Although Ruokokoski never officially joined the November Group, (Marraskuun ryhmä), he participated in the galleries set up by the group.
