"Our House" is a song written by British singer-songwriter Graham Nash and recorded by Crosby, Stills, Nash & Young on their 1970 album Déjà Vu. The single reached #30 on the U.S. Billboard Hot 100and #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.

The song originates in a domestic event that took place while Graham Nash was living with Joni Mitchell (and her two cats) in her house on Laurel Canyon (Los Angeles), after they had gone out for breakfast and had bought an inexpensive vase on Ventura Boulevard. Nash wrote the song in an hour, on Mitchell's piano. In a 2013 interview with Terry Gross on NPR's "Fresh Air", Nash elaborated: “Well, it's an ordinary moment. What happened is that Joni [Mitchell] and I – I don't know whether you know anything about Los Angeles, but on Ventura Boulevard in the Valley, there's a very famous deli called Art's Deli. And we'd been to breakfast there. We're going to get into Joan's car, and we pass an antique store. And we're looking in the window, and she saw a very beautiful vase that she wanted to buy... I persuaded her to buy this vase. It wasn't very expensive, and we took it home. It was a very grey, kind of sleety, drizzly L.A. morning. And we got to the house in Laurel Canyon, and I said – got through the front door and I said, you know what? I'll light a fire. Why don't you put some flowers in that vase that you just bought? Well, she was in the garden getting flowers. That meant she was not at her piano, but I was... And an hour later 'Our House' was born, out of an incredibly ordinary moment that many, many people have experienced".

In the same interview, Nash was asked about the harmonies in the song: "It's me and David [Crosby] and Stephen [Stills] doing our best. That's all we ever do. You know, we're lucky enough to be able to do, you know, anything that we want to do, musically. And, you know, these two guys are incredible musicians. Crosby is one of the most unique musicians I know, and Stephen Stills has got this blues-based, South American kind of feeling to his music. And I'm this, you know, Henry VIII guy from England... You know, it's not supposed to work, but it does, somehow".
