2022 Zavarovalnica Sava Portorož

The 2022 WTA Slovenia Open (also known as the Zavarovalnica Sava Portorož for sponsorship purposes) is a WTA 250 tournament play on outdoor hard courts. It is the 8th edition of the Slovenia Open. The 2022 event took place at the Tennis Club Portorož in Portorož, Slovenia from 12 to 18 September 2022.

The event was held on the second consecutive year in the alternative sporting calendar, however, it was one of the six tournaments that were given single-year WTA 250 licenses in September and October 2022 due to the cancellation of tournaments in China during the 2022 season because of the ongoing COVID-19 pandemic, as well as the suspension of tournaments in China following former WTA player Peng Shuai's allegation of sexual assault against a Chinese government official.
