(October 25, 1821 - March 8, 1891) was a Swiss painter of religious subjects.
Ciseri was born in Ronco sopra Ascona in the canton of Ticino in Switzerland. In 1833 he moved with his father to Florence. He was admitted in 1834 to the Accademia di Belle Arti, where he trained under Niccola Benvenuti. In 1849, he began offering instruction to young painters, and eventually ran a private art school. Among his earliest students was Silvestro Lega.
Ciseri's religious paintings are Raphaelesque in their compositional outlines and their polished surfaces, but are nearly photographic in effect. He fulfilled many important commissions from churches in Italy and Switzerland. Ciseri also painted a significant number of portraits. He died in Florence on March 8, 1891.
