Rupert Charles Wulsten Bunny (29 September 1864 – 25 May 1947) was an Australian painter, born in St Kilda, Victoria.
He achieved success and critical acclaim as an expatriate in fin-de-siècle Paris.
He gained an honourable mention at the Paris Salon of 1890 with his painting Tritons and a bronze medal at the Paris Exposition Universelle in 1900 with his Burial of St Catherine of Alexandria.
He was a "sumptuous colourist and splendidly erudite painter of ideal themes, and the creator of the most ambitious Salon paintings produced by an Australian."
