Helix is a city in Umatilla County, Oregon, United States. The population was 184 at the 2010 census. It is part of the Pendleton–Hermiston Micropolitan Statistical Area. Helix, a geometry term and a part of the ear, was originally to be named Oxford, but the state declined that option when the community's post office was to be named in 1880.
