With a career spanning almost 30 years, the actor achieved success in modelling, TV and film and was known worldwide for his role as Brian O'Conner in the Fast & Furious franchise.
Digital Spy pays tribute to the late star, as we name five of Walker's most memorable movie roles.
The Fast and The Furious
Walker's best known role was undoubtedly that of police officer Brian O'Conner in the Fast & Furious franchise. The actor was propelled to worldwide prominence when he appeared as the undercover agent in 2001's The Fast and The Furious - which grossed over $200 million on a $38 million budget - before reprising the role in all but one of the five sequels.
At the time of his death, Walker was working on the seventh instalment of the series, Fast & Furious 7, which is scheduled for release next year.
An avid supporter of the franchise, Walker recently said that there would be a "guaranteed" eighth Fast & Furious film, as well as hinting that a 9th and 10th could be in the pipeline if it remained successful.
Often considered to be Walker's breakthrough role, the actor starred as high school quarterback Lance Harbor in 1999's Varsity Blues. Manipulated into injecting cortisone into his injured knee, Harbor's injury is made even worse and his promising football career is jeopardised.
Also starring James Van Der Beck and Jon Voight, the movie received nominations at the 1999 Teen Choice Awards and MTV Movie Awards.
She's All That
Continuing his reign of teen movie success, Walker bagged a role in 1999 hit She's All That as Dean Sampson, the best friend of lead character Zack Siler, played by Freddie Prinze Jr.
Walker was in good company as the film's young cast included names who would go on to achieve great success in the industry, including Sarah Michelle Gellar, Anna Paquin and Milo Ventimiglia.
Walker stepped out of his usual action-centric roles in Disney's 2006 adventure drama. He played Jerry Shepard, a guide at an Antarctica research base who is forced to leave his eight trusty sled-dogs behind when he and scientist Davis McLaren (Bruce Greenwood) are caught out in a storm.
A family film (and a bit of a tear-jerker), Eight Below was Walker's biggest commercial hit outside of the Fast movies.
Flags of Our Fathers
The role of Sergeant Hank Hansen - a soldier who participated in the first United States flag raising at the Battle of Iwo Jima - in Clint Eastwood's 2006 remake of Flag of Our Fathers allowed Walker to showcase his versatility as an actor, again moving away from his typecast teen and action roles.
The war drama, also starring Jamie Bell, Ryan Phillippe, John Slattery and Robert Patrick, received critical acclaim.
