Giuseppe Valiani (26 April 1730 in Pistoia – 26 April 1800) was an Italian painter.
He was a pupil of Vincenzo Meucci in Florence. He then traveled with Marchese Francesco Albergati to Bologna, for whom he painted mythological subjects in the Villa at Zola Predosa; these frescoes are considered by many to be his masterpiece. In Bologna, he was soon admitted to the Accademia Clementina, where he was director and for a term, president.[1] He also completed frescoes in houses in Bologna for the Tanari, Merendoni, Pallavicini, Bianchi, and Isolani families. In Venice he painted a ceiling in one of the theaters. In Pistoia, he painted frescoes for the Villa Ippoliti in Merlo, and the Villa Forteguerri in Spazzavento.[2]
His nephew, Bartolomeo Valiani, was his pupil and also a painter.
