1917 Cuyo, provisional designation 1968 AA, is an Amor asteroid, discovered on January 1, 1968 by Carlos Cesco and A. G. Samuel at El Leoncito Observatory, Argentina.^[1]

In 1989, this object was detected with radar from the Arecibo Observatory at a distance of 0.17 AU. The measured radar cross-section was 2.5 km².^[3] Based photometric observations and an assumed medium albedo of 0.15, the near-Earth asteroid measures about 5.7 kilometers in diameter.^[1]

It is named in honor of the Universidad Nacional de Cuyo, which operated the observatory at El Leoncito in collaboration with Columbia and Yale University. Cuyo is also the name of a region in central-west Argentina.^[2]
