24K Magic (stylized as XXIVK Magic) is the third studio album by American singer Bruno Mars. It was released worldwide on November 18, 2016, by Atlantic Records. The follow-up to Mars's successful second album, Unorthodox Jukebox (2012), it explores genres similar to those of its predecessor, such as soul and funk, while Mars and his team focused on capturing the R&B sound that was very popular in the 1990s, described by the singer as the reason he fell in love with music in the first place. Recording sessions for the album took place between fall 2015 and September 2016 at Glenwood Place Studios in Burbank, California. The production of the album was handled by newly formed production trio Shampoo Press & Curl, consisting of Mars, Brody Brown and Philip Lawrence.
The album is considered by some music critics to be influenced by 1980s and early 1990s pop nostalgia. It is also the first album by Mars to enter the R&B and hip hop charts in the United States, ranked by Billboard magazine. As such, the album stayed atop the US R&B albums chart for 21 weeks. Five singles were released from the album: the title track, "That's What I Like", "Versace on the Floor", "Chunky", and "Finesse" (featuring Cardi B). "That's What I Like" became Mars's seventh number-one song on the US Billboard Hot 100. As of November 2018, the album has accumulated three million album-equivalent units in the United States.
On January 28, 2018, at the 60th Annual Grammy Awards, 24K Magic won the awards for Best Engineered Album/Non-Classical, Best R&B Album, and Album of the Year.
As part of promotion for the album, Mars embarked on his third worldwide concert tour, the 24K Magic World Tour (2017–2018).
