Rosalia Price née Masson (fl. 1790), also known as Rosalia Masson-Price and Madame Price, was a British circus artist (acrobat and pantomime artist). She is not to be confused with her sister-in-law Hanne Tott, also called Madame Price.
She was active in Sweden in 1787–1790. Together with her spouse, the acrobat Peter Price (1761-1790), she founded the first circus in Stockholm, Sweden and Scandinavia, and as such has an important place in the history of the circus in Sweden and Scandinavia. Alongside Antonio Bartolomeo Spinacuta, Price are counted as one of two of all of the foreign artists during the Gustavian age who made a lasting effect on the cultural development in Sweden.
