Valentina is the feminine of Valentino — from the Latin valens, meaning "strong" or "healthy." Saint Valentine of Rome (3rd century), whose feast day is February 14, gave the name its romantic association.
Valentina is among the most popular girl's names across Latin America, Italy, Spain, and Eastern Europe. In the U.S. it sits in the top 90 — one of the fastest-rising names of the 2010s and 2020s. The Russian cosmonaut Valentina Tereshkova (born 1937) was the first woman in space.
Valentina reduces to three — the number of bright vitality.
