"Keep On Doin'" is a song recorded by The Isley Brothers, who released the song from their 1970 album, Get Into Something. Though the track's chart performance was modest at best, it would later inspire the funk instrumental, "The Grunt", recorded by James Brown's backing band at the time, The J.B.'s.

Following the early 1969 release of "It's Your Thing", which became a surprise smash hit for them, the Isley Brothers went through a period in 1969 where they went on a stringent recording and touring schedule, recording by day, touring by night, and then recording again after they had finished a show. Between January and December 1969, the brothers would record three consecutive studio albums, a live album, and organize to produce other acts for their T-Neck label, in which inspired by Motown Records and James Brown, they wanted to do things for themselves without the help of label assistance. During this period, Buddah Records agreed to distribute their records for the time being.

Though musically different from "It's Your Thing", the lyrics to "Keep On Doin'" didn't differ from the song as did several songs they would record for the albums, The Brothers: Isley and Get Into Something. This song was recorded in the summer of 1969 with the group's session musicians that they had hired to play on the recordings. Ernie Isley, who had played drums for the band during live gigs starting at age fourteen and had played bass on "It's Your Thing", continued to provide bass guitar work on this song. His other brother Marvin and brother-in-law and best friend Chris Jasper was not part of the recording.

The record was the first single to be released off Get Into Something after Buddah Records picked the song for potential sales, passing over the lengthy title track. Possibly due to the song's repetitiveness, the song only got as high as #75 on the Billboard Hot 100, spending four weeks on the chart before dropping, while it landed at #17 on the R&B singles chart after its release in February 1970.
