Tomasa Ana Núñez Abreu (17 April 1951 – 30 December 1981) was a Cuban track and field athlete who competed in the javelin throw.

Núñez decided to take up athletics in her early teenage years and quickly emerged as a quality thrower with a gold medal at the 1966 Cuban National Scholastic Games after training in Cienfuegos at the School for Student Sport Development (Escuela de Iniciación Deportiva Escolar).

[citation needed] Her first major medal came at age eighteen at the 1969 Central American and Caribbean Championships in Athletics, which was held in Havana that year.

[4] Colón and Menéndez built upon Núñez's legacy by raising it to a global level, becoming Olympic champions.

Núñez died of a sudden illness in 1981 at the age of thirty and was buried at Cementerio de Colón.
