Catarina Ykens-Floquet (1608 – after 1666), was a Flemish still life painter.
She was born in Antwerp as the daughter of Lucas Floquet and the sister of three painters. She married the painter Frans Ykens in 1635 and is known for fruit and flower still lifes, including flower garland paintings. Her works are sometimes confused with the works of a Catarina Ykens born in 1659, who was the daughter of Johannes Ykens in Antwerp.
