The 1991–92 South Pacific cyclone season was an above average tropical cyclone season, with eleven tropical cyclones occurring within the South Pacific basin between 160°E and 120°W. The first tropical cyclone of the season was first noted on November 13, 1991, while the last tropical cyclone dissipated on May 2, 1992. During the season at least 21 people were killed by tropical cyclones, while Tropical Cyclones Cliff and Innis were the only tropical cyclones not to cause any damage to any country in the Southern Pacific.

The 1990–91 South Pacific cyclone season was one of the least active tropical cyclone seasons on record, with only two tropical cyclones occurring within the South Pacific basin to the east of 160°E. The season officially ran from November 1, 1990 to April 30, 1991, with the first disturbance of the season forming on November 23, 1990, while the final disturbance dissipated on May 19, 1991. During the season there were no deaths recorded from any of the tropical cyclones while they were within the basin. However, six people were killed by Cyclone Joy, when it made landfall on Australia. As a result of the impacts caused by Joy and Sina, the names were retired from the tropical cyclone naming lists.
