PK-17 (also known as Firebase Sally) was an Army of the Republic of Vietnam (ARVN) and U.S. Marine Corps and Army base located northwest of Huế, Thừa Thiên Province in central Vietnam.

On 6 April 1967 PK-17 was attacked by People's Army of Vietnam (PAVN) forces, resulting in 2 Marines killed and 7 wounded.

On 2 February the 2nd Battalion, 12th Cavalry Regiment was deployed from Camp Evans to PK-17 to launch an attack towards La Chu to close off the PAVN supply routes west of Huế.

The 2/12th Cavalry was pinned down by superior PAVN forces and eventually broke out on the night of 3 February leaving their dead behind.
