2019–20 ISU Challenger Series

The 2019–20 ISU Challenger Series was held from September to December 2019. It was the sixth season that the ISU Challenger Series, a group of senior-level international figure skating competitions, was held.

Competitions
This season, the series included the following events.

On July 22, 2019, the International Skating Union revoked the Chinese Taipei Skating Union's right to host the Asian Open Figure Skating Classic, scheduled to be held in Taipei, Taiwan. The event was replaced with the Hong Kong Skating Union's Asian Open Figure Skating Trophy. The Sports Administration of the Republic of China ordered the removal of Chinese Taipei Skating Union Secretary-General Eddy Wu for mishandling this situation. The Sports Administration also suspended funding of the Chinese Taipei Skating Union for one year.

Challenger Series rankings
The ISU Challenger Series rankings were formed by combining the two highest final scores of each skater or team.
