Hayward Field is a track and field stadium in the northwest United States, located on the campus of the University of Oregon in Eugene, Oregon. It has been the home of the university's track and field teams since 1921, and was the on-campus home of the varsity football team from 1919 through 1966. Track and field competitions at the stadium are organized by the not-for-profit organization TrackTown USA. Hayward Field was named after track coach Bill Hayward (1868–1947), who ran the Ducks' program from 1904 to 1947. Renovated in 2004, it is one of only five International Association of Athletics Federations Class 1 certified tracks in the United States (along with Hutsell-Rosen Track, Icahn Stadium, John McDonnell Field, and Rock Chalk Park).

A natural grass field was first installed at Hayward Field in 1937; the surface was previously a mixture of dirt and sawdust. That field surface was not unique in the Northwest in the Pacific Coast Conference: Bell Field in Corvallis, Multnomah Stadium in Portland, and Husky Stadium in Seattle made similar transitions to natural grass in this period of time. For most of its existence as a football venue, it was notorious for its poor playing conditions in rainy weather. Despite several improvement efforts, the field didn't drain very well even after the switch to grass, and often turned to mud. In 1949, a 28-row grandstand in the south end zone was constructed; with temporary bleachers in adjacent corners, the venue's capacity was raised to 22,500 for football.
