Zillion

Nick Cannon put this baby name on the map in 2021 when he welcomed a son by the name Zillion Heir (Zillionaire, get it?) — twin to Zion Mixolydian. Zillion is a new addition to the growing trend of numerical -illion names — Million, Billion, Trillion, and even Amillion currently chart for boys.

As a word, Zillion has only existed since 1942, when it was used in Billboard Magazine. Unlike the aforementioned -illion names, it has no real numerical value. Zillion is used in a colloquial sense to refer to extremely large numbers, similar to "jillion" or "gazillion," both of which may attract parents now that Zillion has opened the doors.

Pronounced ZIL-yun.

As of October 2026, Zillion ranked #10684 in US births in 2025 SSA, peaked at #7722 in 2024.
