In Final Fantasy IV, Rosa Farrell (ローザ・ファレル Rōza Fareru?) is the childhood friend of and love interest for Cecil. She is a white mage and archer. Experienced in healing magic, Rosa is often busy attending to Baronian soldiers who have been wounded in battle. When Rosa learns that Cecil was sent to Mist with a bomb ring, she immediately leaves Baron in search of him, but contracts desert fever. Cecil cures her, and she joins his party. During the battle of Fabul, she attempts to save Cecil from Kain, but Golbez kidnaps her and demands the Earth Crystal for her safe return. Cecil brings the Crystal but when the party meets Golbez a fight erupts. Tellah wounds Golbez with the forbidden spell Meteor, but dies in the process and the party is left at the mercy of a wounded Golbez. He is about to slay Cecil but stops and flees. Afterwards, Cecil saves Rosa, and she helps them defeat the Lord of Wind, Barbariccia. Immediately after this, Rosa uses her magic to teleport them out of the unstable tower and she remains in the party for the rest of the game. At the end of the game, she marries Cecil and becomes the Queen of Baron.

After marrying Cecil, Rosa has a son named Ceodore; her pregnancy causes her absence from most of Interlude. In The After Years, she is kidnapped by Kain's dark self. Once back to safety, Rosa joins her old friends as they fight to defeat The Creator.

She is voiced by Yuhko Kaida in Japanese and Kirsty Pape in English.
