2023 Hong Kong Tennis Open

The 2023 Hong Kong Tennis Open (also known as the Prudential Hong Kong Tennis Open for sponsorship reasons) was a professional tennis tournament played on outdoor hard courts. It was the tenth edition of the tournament, and part of the WTA 250 tournaments on the 2023 WTA Tour. It took place in Victoria Park, Hong Kong from 9–15 October 2023. This was the first edition of the tournament held since 2018, as the intervening editions were canceled due to the 2019–2020 Hong Kong protests, the COVID-19 pandemic in Hong Kong, and the WTA's response to the disappearance of Peng Shuai.
