Craig F. Walker is a staff photographer for The Boston Globe. Prior to joining the Globe in 2015, he worked at the Denver Post for 17 years. Before his time out west, Walker was a photographer at Massachusetts newspapers the Berkshire Eagle and The Marlboro Enterprise.

In 2010 Walker's photo essay Ian Fisher: American Soldier, an "intimate portrait of a teenager who joins the Army at the height of insurgent violence in Iraq, poignantly searching for meaning and manhood," won the Pulitzer Prize for Feature Photography. The story was also exhibited at Visa pour l'Image: International Festival of Photojournalism in Perpignan, France.

Two years later Walker was awarded a second Pulitzer Prize for Feature Photography for Welcome Home, The Story of Scott Ostrom, a "compassionate chronicle of an honorably discharged veteran, home from Iraq and struggling with a severe case of post-traumatic stress, images that enable viewers to better grasp a national issue." The same year, Walker was also named Newspaper Photographer of the Year in the Pictures of the Year International competition. 

Walker's photo essay, Raising Connor, was a 2019 finalist for the Pulitzer Prize for Feature Photography, “for superb photography and sophisticated visual storytelling that brought understanding to the story of a young boy living with a complex developmental disability." That year, Walker was also named Photographer of the Year by the Boston Press Photographers Association.
