Meaning & origin
Luiz is a Portuguese variant of Louis that has maintained a modest but consistent presence in the United States since it was first recorded in 1915. The name saw its highest popularity in 2001, when it ranked highest nationally, though it has followed a gradual downward trend since the early 2000s. In 2025, Luiz stands at rank 3,848 with about 1 in 61,003 newborns receiving the name, indicating a decline from its peak. Despite its relative rarity, Luiz retains a strong cultural association with Portuguese- and Brazilian-American communities, though it does not appear among the top-ranked names in any single state.
Luiz is a Portuguese form of the Germanic name Ludwig, derived from the elements hlud meaning 'famous' and wig meaning 'warrior'. It was borne by several European royals and saints over the centuries. In Portuguese, it is a standard equivalent of the English Louis, though the spelling Luís is more common in European Portuguese.
