Sunset at Montmajour is a landscape in oils painted by the Dutch artist Vincent van Gogh on 4 July 1888. It was painted while the artist was at Arles, France and depicts a landscape of garrigue with the ruins of Montmajour Abbey in the background. The painting is 73.3 cm × 93.3 cm. For over 100 years, it was in a Norwegian industrialist's private collection and wrongly assumed to be fake, before being re-examined, authenticated and sold to its current private owner. The painting was temporarily on display from 24 September 2013 until 12 January 2014 as part of an exhibition at the Van Gogh Museum in Amsterdam.

Montmajour Abbey, formally the Abbey of St. Peter in Montmajour, was a fortified Benedictine monastery built between the 10th and 18th centuries on what was originally an island five kilometers north of Arles, in what is now the Bouches-du-Rhône Department, in the region of Provence in the south of France.
