"It's Your Thing" is a funk single by The Isley Brothers. Released in 1969, the funk anthem was an artistic response to Motown chief Berry Gordy's demanding hold on his artists after the Isleys left the label in late-1968.

The lyrics of the chorus, which also serve as first verse, run: "It's your thing/ Do what you wanna do/ I can't tell you/ Who to sock it to". The song is ranked #420 on the Rolling Stone magazine's list of The 500 Greatest Songs of All Time.

After scoring one popular hit with the label with "This Old Heart of Mine (Is Weak for You)", the Isleys felt typecast in the role as a second-tier act while well-established Detroit acts like The Temptations, The Miracles and the Four Tops got more promotion from the label Motown.

The brothers' decision to leave Motown came after a successful UK tour, where the brothers had a bigger fanbase than in America. A re-release of "This Old Heart" had reached number three on the UK pop singles chart. Similar success came with two more singles from their Motown catalog that were hits well after their Motown departure.

Berry Gordy allowed the brothers to leave the label, and the Isleys reactivated their own label, T-Neck Records, which they had originally started a few years prior to their Motown signing. For Buddah Records, the Isleys recorded "It's Your Thing" which Ronald wrote upon arriving home after taking his daughter Tawana to school. The lead singer said that he thought of the melody and some of the lyrics in his head. His older brothers O'Kelly and Rudolph helped compose more lyrics.
