The name Ewiniar (Chuukese: Éwúniyár, [əwɨn̩ijar]) has been used for five tropical cyclones in the Western Pacific Ocean. The name was contributed by the Federated States of Micronesia and is the name of a storm god, literally meaning "waterspout" in Chuukese.

The name Ewiniar was retired following the 2024 Pacific typhoon season and was replaced with Tirou (Chuukese: tirow, [t̪irow]), which refers to a respectful way to say "excuse me" in Chuukese.
