Ohio (Crosby, Stills, Nash & Young song)

"Ohio" is a protest song and counterculture anthem written and composed by Neil Young in reaction to the Kent State shootings of May 4, 1970, and performed by Crosby, Stills, Nash & Young. It was released as a single, backed with Stephen Stills's "Find the Cost of Freedom", peaking at number 14 on the US Billboard Hot 100 and number 16 in Canada. Although live versions of "Ohio" and "Find the Cost of Freedom" were included on the group's 1971 double album 4 Way Street, the studio versions of both songs did not appear on an LP until the group's compilation So Far was released in 1974. The song also appeared on the Neil Young compilation album Decade, released in 1977; his compilation album Greatest Hits, released in 2004; and on his album Live at Massey Hall, recorded in 1971 but unreleased until 2007.

In 2025, the publication Rolling Stone ranked the song at number 9 on its list of "The 100 Best Protest Songs of All Time."
