Ella Marija Lani Yelich-O'Connor (born 7 November 1996), known professionally as Lorde ( LORD), is a New Zealand singer and songwriter. She is known for her unconventional style of pop music and introspective songwriting.

Lorde gained attention performing at a talent show in her early teens. She signed with Universal Music Group (UMG) in 2009 and collaborated with producer Joel Little in 2011. Their first effort, an extended play (EP) titled The Love Club EP, was self-released in 2012 for free download on SoundCloud before it was commercially released in 2013. The EP's single "Royals" reached number one in Canada, New Zealand, the United Kingdom, and the United States, where it spent nine weeks atop the Billboard Hot 100. It sold 10 million units worldwide, making it one of the best-selling singles of all time. Her debut studio album Pure Heroine was released that same year to critical and commercial success. The following year, Lorde curated the soundtrack for the 2014 film The Hunger Games: Mockingjay – Part 1.

Lorde collaborated with producer Jack Antonoff for her second studio album Melodrama (2017), which received widespread critical acclaim and debuted atop the US Billboard 200. The album has since been ranked in Rolling Stone's list of the "500 Greatest Albums of All Time" and Pitchfork's list of the "Greatest Albums of the 2010s". Lorde ventured into indie folk and psychedelic styles for her third studio album, Solar Power (2021). The album reached number one in Australia and New Zealand and the top-10 in numerous other countries, although it polarised music critics and fans alike.

Lorde's accolades include two Grammy Awards, two Brit Awards, and a nomination for a Golden Globe Award. She appeared in Time's list of the most influential teenagers in 2013 and 2014, and the 2014 edition of Forbes 30 Under 30. In addition to her solo work, she has co-written songs for other artists, including Broods and Bleachers. As of June 2017, Lorde had sold over five million albums worldwide.
