The Swarthmore Concert, subtitled King of the Blues, is a live album by the blues musician Lightnin' Hopkins, recorded at the Swarthmore College Folk Festival in 1965.

It was originally released as part of the seven-CD box set Lightnin' Hopkins: The Complete Prestige/Bluesville Recordings, in 1991, before being reissued on Bluesville as a single CD in 1993.

[1][2] AllMusic reviewer Cub Koda stated: "this languished unissued in Fantasy Records' vaults until its release in the early '90s.

That's a shame, because this concert captures Lightnin' at his beguiling best, spinning tales and blues magic with every track.

If you want a disc that clearly showcases Lightnin' Hopkins at his enchanting best, start your collection with this one; it's a charmer".
