The 2022–23 South Pacific cyclone season was a below-average but very destructive tropical cyclone season that featured one of the costliest tropical cyclones in the Southern Hemisphere on record. The season officially started on November 1, 2022, and ended April 30, 2023; however, a tropical cyclone could form at any time between July 1, 2022, and June 30, 2023, and would count towards the season total. During the season, tropical cyclones were officially monitored by the Fiji Meteorological Service, Australian Bureau of Meteorology and New Zealand's MetService. The United States Armed Forces through the Joint Typhoon Warning Center (JTWC) also monitored the basin, issuing unofficial warnings for American interests. The FMS attaches a number and an F suffix to tropical disturbances that form in or move into the basin while the JTWC designates significant tropical cyclones with a number and a P suffix. The BoM, FMS and MetService all use the Australian Tropical Cyclone Intensity Scale and estimate windspeeds with a period of approximately ten minutes, while the JTWC estimates sustained winds over a 1-minute period, which are subsequently compared to the Saffir–Simpson hurricane wind scale (SSHWS).

The 2022–23 Australian region cyclone season was the fourth consecutive season to have below-average activity in terms of named storms. The season officially started on 1 November 2022 and finished on 30 April 2023, however, a tropical cyclone could form at any time between 1 July 2022 and 30 June 2023 and would count towards the season total, as Tropical Cyclone 01U proved in July 26. During the season, tropical cyclones were officially monitored by one of the three tropical cyclone warning centres (TCWCs) for the region which are operated by the Australian Bureau of Meteorology, National Weather Service of Papua New Guinea and the Indonesian Agency for Meteorology, Climatology and Geophysics. The United States Joint Typhoon Warning Center (JTWC) and other national meteorological services including Météo-France and the Fiji Meteorological Service also monitored the basin during the season.
