Meaning & origin
Viliami is a Tongan form of William, carrying the meaning 'resolute protector' from its Germanic roots. First recorded in U.S. data in 1980, the name has been steadily rising in use since 1997, with a peak in 2020. In 2025, it ranked 5208, with about 1 in 94893 male births receiving the name. The name's strongest concentration is in Utah, reflecting the Tongan diaspora community there. Viliami remains relatively uncommon, offering a distinctive cultural choice that honors Tongan heritage while connecting to the classic Western name William.
Viliami is the Tongan form of William, which is derived from the Germanic elements 'wil' (will, desire) and 'helm' (helmet, protection). The name was introduced to the Pacific islands by Christian missionaries and has since become a given name in Tonga and among Tongan diaspora communities.
