The 2000–01 South Pacific cyclone season was an event in the annual cycle of tropical cyclone formation. It began on November 1, 2000, and ended on April 30, 2001. These dates conventionally delimit the period of each year when most tropical cyclones form in the southern Pacific Ocean east of 160°E. Additionally, the regional tropical cyclone operational plan defines a tropical cyclone year separately from a tropical cyclone season, and the "tropical cyclone year" runs from July 1, 2000, to June 30, 2001.
