The Hong Kong Tennis Open, due to start on 5 October, has been postponed because of ongoing protests.
The organizers said they would be better placed to have a "smooth running tournament...[at a] later time".
Hong Kong has for months been rocked by increasingly violent protests, triggered by an extradition bill.
The bill has now been withdrawn but the protests have continued and have grown to reflect wider demands for democratic reform.
The Hong Kong Tennis Open was originally due to take place between 5-13 October.
"In light of the present situation, the event will no longer take place," the Hong Kong Tennis Association and the Women's Tennis Association (WTA) said in a statement.
They said they were in "active discussion" to find a later date for the tournament.
The announcement comes as Hong Kong braces itself for another weekend of protests.
Hong Kong police have not given permission for a rally scheduled for Sunday, but it is expected to take place anyway.
