Nicolau is a distinctive and traditional given name, derived from the Latin 'Nicolaus', which means 'victory of the people'. It is widely recognized as the Portuguese and Catalan form of Nicholas, reflecting its continental European origins. The name Nicolau gained prominence in medieval times due to Saint Nicholas, the historic bishop and gift-giver who became a model for modern-day Santa Claus. This name has been popular throughout history, carried by notable figures such as Nicolaus Copernicus, the 15th-century mathematician and astronomer who proposed the heliocentric model of the universe. Today, Nicolau continues to be celebrated as a classic choice for parents seeking a timeless yet unique name for their child.
Nicolau saw an increase in popularity between 2018 and 2023, with five babies named Nicolau born each year.
