Gaston is a Belgian gag-a-day comic strip created in 1957 by the Belgian cartoonist André Franquin in the Franco-Belgian comics magazine Spirou. The series focuses on the everyday life of Gaston Lagaffe, a lazy and accident-prone office junior who works at Spirou's office in Brussels. Gaston is very popular in large parts of Europe and has been translated into over a dozen languages, but except for a few pages by Fantagraphics in the early 1990s, there was no English translation until Cinebook began publishing English language editions of Gaston books in July, 2017.

André Franquin was an influential Belgian comics artist, whose best-known creations are Gaston and Marsupilami. He also produced the Spirou et Fantasio comic strip from 1946 to 1968, a period seen by many as the series' golden age.
