Déjà Vu, is the second studio album by American folk rock group Crosby, Stills & Nash, and their first as a quartet with Neil Young. Released in March 1970 by Atlantic Records, it topped the pop album chart for one week and generated three Top 40 singles: "Woodstock", "Teach Your Children", and "Our House". It was re-released in 1977 and an expanded edition was released in 2021 to mark its fiftieth anniversary.

"Our House" is a song written by British singer-songwriter Graham Nash and recorded by Crosby, Stills, Nash & Young on their album Déjà Vu (1970). The single reached No. 30 on the U.S. Billboard Hot 100 and No. 20 on the Cash Box Top 100. The song, "an ode to countercultural domestic bliss", was written while Nash was living with Joni Mitchell, recording both Crosby, Stills & Nash and Déjà Vu.
