The baby name Guilherme is a Male name , 3 syllables long and is pronounced /ɡiˈʎeɾmi/ (Portuguese, approx. "gee-LYEHR-mee"); English approximation: /ɡɪˈlɛərmi/ ("gih-LAIR-mee").

Guilherme is Portuguese in Origin.

Guilherme is the Portuguese form of William, ultimately from the Proto-Germanic elements wil “will, desire” and helm “helmet, protection.” The name entered Iberia through the Latinized Gulielmus and Old French Guillaume, spreading with medieval church and knightly networks. It appears in Portuguese records from the 12th–13th centuries and endured via devotion to saints such as William of Gellone and William of Maleval. In Brazil, usage rose sharply from the late 19th century and remains common across the Lusophone world, carrying the sense of a “resolute protector.”

International variants include William (English), Guillaume (French), Guillermo (Spanish), Guglielmo (Italian), Wilhelm/Vilhelm (Germanic and Nordic), Willem (Dutch), Vilém (Czech), and Uilliam/Uilleam (Irish/Scottish Gaelic); Liam is a widespread short form. Portuguese nicknames are typically Gui, with bilingual circles sometimes using Will. Feminine counterparts are Guilhermina and Wilhelmina.
