Mark Daniel Ronson (born 4 September 1975) is a British-American musician, DJ, record producer, songwriter, and remixer.

Ronson served as lead and executive producer for the soundtrack to the 2023 fantasy comedy film Barbie, on which he also composed and co-wrote several of its songs with his production partner Andrew Wyatt.

While attending New York University, Ronson became a popular DJ in the regional area for his work in hip hop music.

He signed with Elektra Records to release his debut studio album, Here Comes the Fuzz (2003), which contained guest performances from prominent American hip hop acts and was met with lukewarm commercial reception.

Due to this, he parted ways with Elektra the following year and co-founded his own label, Allido Records, through which he released his following projects and signed other artists including Wale, Rhymefest, and Daniel Merriweather.

By 2006, he gained wider recognition for his production work on albums and singles for Lily Allen, Christina Aguilera, and Amy Winehouse.

It peaked at number two on the UK Albums Chart earned him the Brit Award for British Male Solo Artist.

His 2014 single "Uptown Funk" (featuring Bruno Mars), yielded his furthest commercial success internationally, spending 14 consecutive weeks atop the U.S.

[29] Ronson's debut album, Here Comes the Fuzz, was released in 2003 and according to a retrospective review "the record sold poorly and (...) critical reception was lukewarm at best, dismissive at worst".

[30] The album featured performances from artists from diverse genres, including Mos Def, Jack White, Sean Paul, Nappy Roots and Rivers Cuomo.

[38] The cover album Version appeared on his own label with Alexis Petridis describing the song interpretations as "an affectionate pastiche of a 60s soul revue's brass-laden sound".

On 23 June, Ronson made the cover of The Guardian newspaper's Guide magazine, alongside singer Lily Allen.

In late 2007, he focused on production, working with Daniel Merriweather on his debut album, and recording again with Amy Winehouse and Robbie Williams.

He also performed a medley of Coldplay's "God Put a Smile upon Your Face" with Adele, "Stop Me" with Daniel Merriweather, and "Valerie" with Amy Winehouse.

[62] Ronson also co-wrote the song "Shallow" for the film A Star Is Born with his frequent collaborators Lady Gaga, Andrew Wyatt, and Anthony Rossomando.

Ronson has described the album as a collection of "sad bangers," with the title track laying down a warm mid-tempo dance groove under Li's melancholy vocals.

[69] In addition to executive producing the album, Ronson also served as co-producer and co-writer on several of the tracks, including "Dance the Night",[70] "What Was I Made For?

[83][82] On 3 September 2011, Ronson married French actress and singer Joséphine de La Baume, who had previously appeared in the music video for "The Bike Song".
