Hilo (/ˈhiː.loʊ/, HEE-low; Hawaiian pronunciation: [ˈhilo]) is the largest settlement in and the county seat of Hawaiʻi County, Hawaii, United States, which encompasses the Island of Hawaiʻi, and is a census-designated place (CDP). The population was 44,186 according to the 2020 census. It is the fourth-largest settlement in the state of Hawaiʻi, the largest settlement in the state outside of Oahu, and the largest settlement in the state outside of the Greater Honolulu Area.

Hilo is in the District of South Hilo. The city overlooks Hilo Bay and has views of two shield volcanoes – Mauna Loa, the largest active volcano on the planet, and Mauna Kea, the highest point in the Hawaiian Islands. The Hilo bayfront has been destroyed by tsunamis twice. The majority of human settlement in Hilo stretches from Hilo Bay to Waiākea-Uka, on the flanks of the volcanoes.

Hilo is home to the University of Hawaiʻi at Hilo, ʻImiloa Astronomy Center, as well as the Merrie Monarch Festival, a week-long celebration, including three nights of competition, of ancient and modern hula that takes place annually after Easter. Hilo is also home to the Mauna Loa Macadamia Nut Corporation, one of the world's leading producers of macadamia nuts. Hilo is served by Hilo International Airport.
