"Marry You" is a song by American singer and songwriter Bruno Mars from his debut studio album, Doo-Wops & Hooligans (2010). Written and produced by The Smeezingtons, the track serves as the record's sixth track and was released as Mars's fourth single outside of the United States. "Marry You" is a pop song featuring strong influences of doo-wop and soul music. The recording focuses on spontaneous marriage and therefore, since its release, has frequently been used as a proposal song.

"Marry You" received generally positive reviews from music critics, with some complimenting its production and its reminiscence of 60's pop style. Some criticized a perceived lack of creativity. Despite not being released as a single in the US, the song charted at number 85 on the Billboard Hot 100 and has since sold 2.2 million copies there. It charted on most international markets within the top fifteen, reaching number 10 on the Canadian Hot 100, number 8 in Australia, the top five in New Zealand, and charting at number 11 in the United Kingdom. The single was certified three times platinum by Music Canada and two times platinum by the Australian Recording Industry Association. Mars performed "Marry You" on both of his worldwide tours, The Doo-Wops & Hooligans Tour (2010–12) and the Moonshine Jungle Tour (2013–14). The song has been covered a number of times, most notably by the cast of Glee; their cover outperformed the original song by reaching number 32 on the Billboard Hot 100.

"Marry You" is one of the eleven songs composed and produced by The Smeezingtons, the collaboration of Bruno Mars, Philip Lawrence, and Ari Levine, for Mars's debut studio album, Doo-Wops & Hooligans. Lawrence explained the inspiration behind the song in an interview with American Songwriter stating, "[w]e had this image of a slow-mo video in Vegas of a couple running, and she’s in her gown and he’s in his tux, the wedding party is behind them and everyone’s raging. This sort of crazy, daring, wedding feeling". Lawrence was surprised at the impact of the song after watching some YouTube videos. He stated that "[w]e always thought it was a good song and catchy, but we didn’t think it would affect pop culture the way that it has. The first time we saw one of those YouTube videos, it changed everything for us. We were almost in tears, just the power of music... the power of what it is we can create. These ideas, words, and lyrics and how they can get into the fabric of society and affect people’s lives in such an amazing way."
