The track, whose title has yet to be announced, will debut at 4.23pm on various UK radio stations, including Radio 1.
It will premiere simultaneously in New York, where local time will be 11.23am - a figure which corresponds with the November 23 (11-23) release date of Rihanna's new album.
The album, also currently untitled, is the follow-up to 2007's Good Girl Gone Bad, which sold more than seven million copies worldwide and spawned eight UK top 40 hits.
To enable fans to track time until the single premiere, Mercury Records has created a special online countdown widget, which appears below:
