Tammar Luxoro (February 11, 1825 – November 25, 1899) was an Italian painter, mainly painting landscapes on site.
He enrolled in the Accademia Ligustica of Fine Arts in 1842, and studied under the vedutista Domenico Pasquale Cambiaso.
Among his influences were that of the Swiss Alexandre Calame, the Bellunese Ippolito Caffi, and later (1854–1857) in Luxoro's career, Antonio Fontanesi.
Among Luxoro's colleagues in landscape painting were Ernesto Rayper, Alfredo d'Andrade, and the Spaniards Serafino D'Avendano and Alberto Issel.
He became professor of his alma mater, teaching landscape painting, and was named to various commissions for the protection of monuments and architecture.
