Acting career
1983–1989: Early roles and breakthrough
At 17, Dempsey got an audition for a role in the stage production of Torch Song Trilogy, which led to Patrick Dempsey's discovery as an actor in 1983. His audition was successful and he spent the following four months touring with the company in Philadelphia. He followed this with another tour, Brighton Beach Memoirs, in the lead role, which was directed by Gene Saks. Dempsey has also made notable appearances in the stage productions of On Golden Pond, with the Maine Acting Company, and as Timmy (the Martin Sheen role) in a 1990 off-Broadway revival of The Subject Was Roses co-starring with John Mahoney and Dana Ivey at the Roundabout Theatre in New York.

He then co-starred in the third installment of the comedy classic Meatballs III: Summer Job, alongside Sally Kellerman in 1987. This was followed by the teen comedy Can't Buy Me Love in 1987 with actress Amanda Peterson and Some Girls with Jennifer Connelly in 1988.

Dempsey made several featured appearances in television in the 1990s; he was cast several times in pilots that were not picked up for a full season, including lead roles in the TV versions of the films The Player and About A Boy. He received positive reviews, however, as he portrayed real-life mob boss, Meyer Lansky in 1991 when Mobsters was put on the screen. His first major television role was a three-episode stint as Will Truman's closeted sportscaster boyfriend on Will & Grace. He appeared in four episodes of Once & Again as Aaron Brooks, the schizophrenic brother of Lily (Sela Ward). Dempsey received an Emmy nomination in 2001 as Outstanding Guest Actor in a Drama Series for the role of Aaron. In 1993, he played a young John F. Kennedy in the two-part TV mini-series JFK: Reckless Youth. In 2000, he played Detective Kincaid in Scream 3. The relationship his character had with Meredith Grey (Ellen Pompeo) on screen has received a lot of praise and positive reactions.
In 2007, Dempsey starred in the Disney film Enchanted, and the Paramount Pictures film Freedom Writers, where he reunited with his Iron Jawed Angels co-star Hilary Swank. He also voiced the character Kenai in Brother Bear sequel Brother Bear 2, replacing Joaquin Phoenix. Other roles Dempsey appeared in during this time include the 2008 film Made of Honor as Tom, and the 2010 romantic comedy Valentine's Day; the latter film follows five interconnecting stories about Los Angelinos anticipating (or in some cases dreading) the holiday of love. Universal Pictures acquired the rights to the prize-winning novel The Art of Racing in the Rain in July 2009, for Dempsey to star in. The film instead starred Milo Ventimiglia. He starred as Dylan Gould in Transformers: Dark of the Moon (2011).
In January 2014, he signed a two-year contract to remain on Grey's Anatomy, then in its tenth season, that would ensure his participation for potential 11th and 12th seasons. Dempsey was nominated for Best Actor – Television Series Drama at the 2006 Golden Globe Awards for the role. His success on the show has led to his becoming a spokesman for Mazda and State Farm Insurance. BuddyTV ranked him #1 on its list of "TV's Sexiest Men of 2011". In November 2020, Dempsey appeared as Derek Shepherd at the start of the series' 17th season for the first time since the character had died in April 2015.
2016–present
Following his departure from Grey's Anatomy, Dempsey was working on two small-screen projects: a drama The Limit for SundanceTV and a travelogue spy thriller called Fodors. He said:
In 2016, Dempsey starred in the Universal Pictures film Bridget Jones's Baby with Renée Zellweger and Colin Firth, and in 2018 he appeared on Epix television miniseries The Truth About the Harry Quebert Affair. In 2017 he participated in the short film Red Nose Day Actually, a sequel to the 2003 romantic comedy Love Actually. Dempsey played the role of the husband of Laura Linney's character Sarah. Starting from 2020 he has portrayed Dominic Morgan in the Sky Atlantic financial thriller series Devils. On February 4, 2020, Dempsey signed on to star as the lead of a CBS political drama pilot Ways & Means, where he would portray a Congressional leader. Initially planned to be considered for the 2020–21 televisions season, the pilot was rolled into consideration for the following season due to the COVID-19 pandemic. CBS ultimately passed on the finished pilot in May 2021. In January 2021, it was announced that Dempsey would reprise his role in the Enchanted sequel, Disenchanted, which began production in spring of that year. The film was released on Disney+ in late 2022. In 2023, he portrayed Sheriff Eric Newlon in the slasher film Thanksgiving and Piero Taruffi in the biographical sports drama Ferrari directed by Michael Mann. In 2024, Dempsey portrayed police captain Aaron Spencer in the prequel series Dexter: Original Sin. He currently stars as Angelo in the Fox series Memory of a Killer
Auto racing

In 2014, Dempsey told Reuters in the Hockenheimring support paddock at the German Grand Prix that motor racing was not just a hobby, and had become as much a part of who he is as acting. He said, "It's all-consuming in many ways. I couldn't imagine not racing right now. It really keeps me motivated. It's all I think about on a daily basis."
Dempsey, who maintains an extensive sports and vintage car collection, has enjoyed auto racing in his spare time for several years. Before the 24 Hours of Le Mans in 2013, he said that he would like to compete full-time, telling Eurosport:
<blockquote>I would like to make that [motorsports] a complete priority and just focus on this full-time. If I could just walk away from acting, I think I could do that very easily, and just focus on the driving, I would love that more than anything else.</blockquote>

Dempsey has competed in prestigious events such as the 24 Hours of Le Mans and Rolex 24 at Daytona sports car races, and the Tecate SCORE Baja 1000 off-road race. He was a co-owner of the Vision Racing IndyCar Series team and current owner of Dempsey Racing, which is presently racing two Porsche 911 GT America's in the Tudor United Sports Car Series. He participated in this series as often as his schedule allowed, although insurance restrictions kept him from driving competitively while also filming a motion picture. In 2009, he raced a Team Seattle Advanced Engineering Ferrari F430 GT in the 2009 24 Hours of Le Mans's GT2 class and finished ninth in class.
Dempsey announced he would race the 2011 Rolex 24 at Daytona along with other races throughout the season in a Mazda RX-8. Dempsey finished in third place in the GT Class of the Rolex 24 at Daytona. In 2012, Dempsey competed in the Grand-Am Continental Tire Sports Car Challenge behind the wheel of an Aston Martin Racing-Multimatic Motorsports Aston Martin Vantage GT4, which, after five successful racing seasons in Europe, was to make its debut on American tracks. He formed the Dempsey Racing team to compete in the American Le Mans Series. The team fielded a full-time Oreca FLM09 in the Prototype Challenge class as well as a Lola B12/80 coupe in the Prototype 2 class from Laguna Seca onward.
After debuting at the 2009 24 Hours of Le Mans, Dempsey returned to France four years later and competed in a Porsche 997 GT3 RSR at the 2013 24 Hours of Le Mans endurance race. Dempsey and his co-drivers finished 29th overall and fourth in-class. In 2015, Dempsey focused on participating in the FIA World Endurance Championship with his own Dempsey Racing-Proton team in the GTE-Am class in a Porsche 997 GT3 RSR, teamed with Patrick Long
