The actress, 25, has reportedly been spending time with 35-year-old tech manager William "Mack" Knight over the past few months.
According to The Sun, the Harry Potter actress spent a weeklong romantic getaway with Knight, relaxing at popular vacation spot Big Sur, in California. There, they took full advantage of the amenities, going on scenic hikes and soaking up the sunshine at luxurious hotel Post Ranch Inn.
Watson's rep declined to comment.
This isn't the first time the pair have been spotted out – they were photographed together last fall.
In October, the two were seen leaving the Richard Rodgers Theatre in New York City after catching the hit Broadway production Hamilton. The two looked comfortable and casual as they walked out of the theater, with Watson wearing black jeans and a white shirt, while Knight sported a pair of blue jeans and a sweater.
According to his LinkedIn profile, Knight is a Princeton graduate who also attended Columbia Business School in Manhattan. He's spent almost five years working at Medallia Professional Services, which specializes in customer feedback and where he is currently a senior manager.
"Tech/entrepreneurship enthusiast, business school grad, writer, artist, photographer, adventurer, naturalist, etc. Many passions. 160 characters won't cut it," reads one of his online profiles, which features a handful of Knight's Instagram photos – including a few from his vacation in Big Sur.
This is Watson's first reported relationship since her "horrendous" split from ex-boyfriend Matthew Janney in December 2014.
"I felt really uncomfortable," she told Vogue U.K. of being single. "Even before my relationship ended, I went on a silent retreat, because I really wanted to figure out how to be at home with myself."
