Apotheosis of Saint Sebastian is a circa 1725 oil on canvas painting by the Italian Baroque painter Sebastiano Ricci.

[2] The painting has been called "magnificent, one of Sebastiano Ricci's most perfect achievements" (l'oœuvre est magnifique, elle compte parmi les plus parfaites réussites de Sebastiano Ricci) by the art historian Pierre Rosenberg, writing in 1984.

It is a late version of a theme that Ricci had treated between 1696 and 1698 in a now destroyed fresco in St Sebastian Church, Venice.

[1] Apotheosis of Saint Sebastian was given to the museum in 1994 by the collectors Othon Kaufmann and François Schlageter, together with another painting by Ricci and several other Italian works, among which Crespi's L'Ingegno, and Vignali's Cyparissus.

The painting had belonged to the Dukes of Buccleuch and was sold in 1953 as part of the estate of Rodney Matthews-Napier, an Australian who had married a member of that aristocratic family.
