After the Gold Rush is the third studio album by the Canadian-American musician Neil Young, released in September 1970 on Reprise Records. It is one of four high-profile solo albums released by the members of folk rock group Crosby, Stills, Nash & Young in the wake of their chart-topping 1970 album Déjà Vu. Young's album consists mainly of country folk music along with several rock tracks, including "Southern Man". The material was inspired by the unproduced Dean Stockwell and Herb Bermann screenplay After the Gold Rush.
