Júlia Peraire (born Júnia Peraire i Ricarte in 1888 - 1941) was Modernist painter Ramon Casas' muse, lover and wife.
She appears in more than 120 paintings and drawings for over 25 years.
She came from a modest family and had a very strong personality. They met in 1905 when she was just 17 and he was 39. It was in the Maison Dorée cafe, where she was an amulant seller, and they met there by chance.
He split with his long relationship Emilia Huet and began to date the young Júlia. All his family opposed the relationship, and it wasn't until his mother died in 1912 that Casas and Perarire went to live together. Ten years later, in 1922, they married. He lost a sister and was ill. They didn't have any children.
