Greatest Hits, Vol. 3 is a greatest hits compilation by country singer Johnny Cash, released on Columbia Records in 1978 (see 1978 in music). It is the third and last part of the Johnny Cash Greatest Hits compilation series; the previous parts, Greatest Hits, Vol. 1 and Greatest Hits, Vol. 2, had been released in 1967 and 1971, respectively. The release is notable in that it contains two songs - "It's All Over" and "Old Time Feeling," - which hadn't appeared on any Johnny Cash album before.
