Deroi is French in Origin.

Deroi is a French-based given name formed from de + roi, literally “of the king.” Roi comes from Old French roi “king,” ultimately from Latin rex/regis, giving Deroi meanings such as “royal” or “belonging to the king.” The compact spelling modernizes the older surname phrase De Roi while preserving its aristocratic nuance.

As a surname in medieval France, De Roy signaled residence on royal lands or service within a royal household, and it traveled to North America with French and French-Canadian settlers. As a given name, Deroi remains rare but aligns with the 19th–20th‑century trend of adopting regal French surnames - seen with Leroy and Deroy - particularly in African American and Creole communities. Documented variants and cognates include Deroy, DeRoy, De Roi, Leroy/LeRoy, Roi, and Roy; less common feminized or stylistic forms such as Leroya also appear. The name conveys dignity and heritage with a succinct, modern profile.
