The tech giant had initially planned to unveil the operating system on June 3, but amid violent protests across cities in the US, Google has decided to delay the launch.
A statement said: "Now is not the time to celebrate."
Despite this, Google hasn't confirmed specifically whether the protests are the reason for the delay.
By contrast, Sony still plans to launch games for the new PlayStation 5 on June 4.
Piers Harding-Rolls, from Ampere Analysis, told the BBC: "If the PS5 event goes ahead without a delay, and clearly the ongoing protests in the US means that a delay is possible, I'm expecting a strong showing from Sony.
"The company is pressing ahead with a global launch and while there will have been some disruption to games production due to Covid-19, with months to go before release it is easier to rectify the development schedules to catch up."
At present, the PlayStation 5 console is set for release later this year.
