Guillermina (feminine form) is Spanish in Origin.

Guillermina is the Spanish feminine form of Guillermo, descended from the Germanic Wilhelm (wil “will, desire” + helm “helmet, protection”). The meaning is commonly rendered as “resolute protector” or “steadfast guardian,” retaining the martial-protective sense of the medieval name while adapting it to a Romance-language feminine ending.

In Iberian usage the form appears by the early modern period and became more familiar in the 19th and early 20th centuries across Spain and Latin America, a rise paralleled by broader European awareness through Wilhelmina of the Netherlands. Variants include Wilhelmina (English, German, Dutch, Scandinavian), Guilhermina (Portuguese), Guglielmina (Italian), and the much rarer Spanish Guillerma. Nicknames and short forms include Mina and, informally, Guille. Today Guillermina reads classic and distinctive, balancing Old World gravitas with approachable diminutives and periodic vintage revivals in Spanish-speaking communities.
