The 2021 WTA Slovenia Open (also known as the Zavarovalnica Sava Portorož for sponsorship purposes) was a WTA 250 tournament played on outdoor hard courts. It was the 7th edition of the Slovenia Open, last held in 2010. It was primarily organised due to the cancellation of the Asian tournaments during the 2021 season because of the ongoing COVID-19 pandemic. The 2021 event took place at the Tennis Club Portorož in Portorož, Slovenia from 13 to 19 September 2021.
