Paul Williams is a fictional character on the American CBS soap opera The Young and the Restless. Paul was introduced to the show on May 23, 1978, and has been portrayed by Doug Davidson until 2020. Initially, Paul was a "bad boy", who had a romance with Nikki Reed, giving her an STD. The relationship ended, but the two have remained friends since. After a year on the series, Bell gave the character a proper backstory, surname and family. This included his notoriously unstable sister Patty Williams. After a failed marriage to April Stevens —who gave birth to his daughter Heather Stevens —focus turned towards Paul's career as a private investigator, as well as his relationship and eventual marriage to and later divorce from Lauren Fenmore. Paul's string of unsuccessful romances with women—including his ill-fated bride Cindy Lake, and Cassandra Rawlins, the wife of one of his clients—continued. Over the years, Paul continued to become heavily involved in various storylines as a private investigator.
