Betty Hill (July 28, 1919 – October 17, 2004) and Barney Hill (March 20, 1922 – February 25, 1969) were an American couple who reported being abducted by extraterrestrial beings on the night of September 19–20, 1961, while driving home to Portsmouth, New Hampshire from a vacation in Montreal. Their case became the first widely publicized alleged alien abduction in the United States and helped define many of the cultural templates associated with abduction accounts.

The Hills reported observing a large craft with lit windows following their car on a rural highway. Barney stopped the vehicle and, looking through binoculars, described seeing uniformed figures through the craft's windows before fleeing in panic. The couple then experienced approximately two hours of "missing time" before arriving home. They subsequently reported anxiety, unusual dreams, and physical anomalies including stained clothing and scuff marks on Barney's shoes.

Their experience came to wider attention after Betty's dreams of being examined aboard a craft were discussed with Dr. Benjamin Simon, a Boston psychiatrist who used hypnotic regression to explore their accounts. Under hypnosis, both independently described being examined by humanoid beings with large eyes aboard a craft. Betty additionally described being shown a "star map" she later sketched from memory, which some researchers have compared to the Zeta Reticuli star system.

Their story was first publicized in a 1965 newspaper series and later in John Fuller's book The Interrupted Journey (1966). The Hills were a socially prominent couple: Betty was a social worker and racial justice activist; Barney was an employee of the U.S. Postal Service and served on the New Hampshire Civil Rights Commission. Their credibility and respectability made their case particularly impactful in public perception of the abduction phenomenon.
