Jeanine Christelle Djomnang, 26, goalkeeper of Femina Stars collapsed and died during a warm-up session.
The Cameroon Football Federation who confirmed the news said she died on her way to the hospital in southern Cameroon on Sunday.
The federation however said it was awaiting a medical report even though initial reports suggest she died of a heart attack.
Djomnang reportedly complained of chest pains as her team prepared for MINPROFF Yaounde in the Cameroon elite league and was taken to hospital.
Her death comes just days after Cameroon player Patrick Ekeng died in Romania.
