Dan Bullock (December 21, 1953 – June 7, 1969) was a United States Marine and the youngest U.S. serviceman killed in action during the Vietnam War, dying at the age of 15.

[3] When Bullock was 14 years old, he altered the date on his birth certificate to show that he was born on December 21, 1949.

Less than a month later on June 7, 1969, Bullock and three other Marines were occupying a bunker near the base airstrip when a People's Army of Vietnam sapper unit attacked the base at night, throwing a satchel charge into the bunker killing three Marines; Bullock was just 15 years old.

[10] On June 7, 2003, a section of Lee Avenue in Brooklyn, where Bullock had lived since age 11, was renamed in his honor.

In 2019, a North Carolina state historical marker honoring his life was erected near his childhood home in Goldsboro near 200 West Ash Street.
