Dale Richard Buis (August 29, 1921 – July 8, 1959) was a United States Army officer.

He was part of the Military Assistance Advisory Group (MAAG) sent in 1955 to train South Vietnamese troops.

On 8 July 1959 he was visiting the MAAG 7 base at Biên Hòa, 20 miles (32 km) northeast of Saigon.

Six Viet Cong (VC) attacked the mess hall where he and four other officers were watching the movie The Tattered Dress.

The wounded included Captain Howard Boston (MAAG 7) and the South Vietnamese cook's eight-year-old son.
