Hugh Nanton Romney Jr., known as Wavy Gravy, is an American entertainer and peace activist best known for his role at Woodstock, as well as for his hippie persona and countercultural beliefs.

The Hog Farm is an organization considered America's longest running hippie commune. Beginning as a collective in North Hollywood, California, during the 1960s, a later move to an actual hog farm in Tujunga, California gave the group its name. Founded by peace activist Hugh Romney and his actress wife Jahanara Romney, the Hog Farm evolved into a "mobile, hallucination-extended family", active internationally in both music and politics. A documentary short The Hog Farm Movie, filmed in 1967/68, was digitally restored in July 2019.
