Rita Myrat (real name: Margarita Tarsouli, 1911–1985) was a Greek film and stage actress. With a career spanning about 40 years, she participated in 53 performances of the National Theatre (1933–1970), while her filmography includes only 5 films (1930–1963).

She appeared in the theatre for the first time in 1932, with the play While the Ship Sails by Galatea Kazantzakis, which was staged on the Main Stage of the National Theatre, directed by Fotos Politis, alongside Sappho Alkaios and Manos Katrakis.

She made her film debut in 1930, with the film The Lagiarni directed by Ioannis Loumos. The same year, she appeared in the film The Blue Candles, directed by Michalis Kounelakis. Her return to cinema came after almost 20 years with the film The Duchess of Placentia in 1956, directed by Maria Plyta, where she played Sophie de Marbois-Lebrun, also known as the Duchess of Placentia.

In 1962, she appeared in the film The Loustrakos, again directed by Maria Plyta, while a year later she made her last appearance in the film The Great Secret, directed by Dimitris Sklavos.
