"Devil Was in My Yard" is a song by Australian group The Sleepy Jackson. It was released 25 September 2006, in Australia, as the second and final single from the group's second album Personality – One Was a Spider, One Was a Bird. The music video, released on 31 July, was directed by Sarah-Jane Woulahan and Sean Gilligan (Squareyed Films).

Luke Steele explaining "It was only after I’d worked on the songs for a while that I realized they were all to do with the conflicting sides of my personality. When they first come to me they seem to be about specific incidents to do with our last manager and things in the band going haywire. But after a while they go into another realm. I realised they were more to do with the spiritual conflict between God and the Devil. I surprised myself with how angry and intense they were. But I like that paradox; uplifting tunes with these lyrics about struggle and resolution.”

Steele in an interview in Clash goes onto to state "There's trials and tribulations in the lyrics (but) everyone in life gets thrown every single day; someone's gonna die or someone’s gonna rip your face off. You can’t get through life without these things. It's not like you’ve gotta wait for them, you can't go looking for the devil – you’ll certainly get it."
