Melodrama is the second studio album by New Zealand singer-songwriter Lorde. It was released on 16 June 2017 by Lava and Republic Records and distributed through Universal. Following the breakthrough success of her debut album Pure Heroine (2013), Lorde retreated from the spotlight, and travelled between New Zealand and the United States. Initially inspired by her disillusionment with fame, she wrote Melodrama to capture heartbreak and solitude after her first breakup.

Lorde chose Jack Antonoff as the main collaborator because she felt the need to expand her artistry from the Joel Little-produced Pure Heroine. The final product is an electropop record incorporating piano-based melodies, pulsing synthesisers and dense electronic beats. Critics viewed the album as a maximalist departure from the minimalist hip hop-influenced production of its predecessor, and considered it a loose concept album chronicling the emotions ensued from a house party. The songs "Green Light", "Perfect Places", and "Homemade Dynamite" were released as singles. Lorde promoted the album through several music festivals she headlined, and the Melodrama World Tour in 2017 and 2018.

The album was Lorde's first number one in the United States and Canada, and also peaked atop the charts in Australia and New Zealand. It received gold or platinum certifications in the said countries and the United Kingdom. Melodrama received universal acclaim from music critics who complimented its sound and Lorde's vocals and direct songwriting; it was featured on various year-end and decade-end lists. It won a New Zealand Music Award for Album of the Year, and received a nomination for Album of the Year at the 60th Annual Grammy Awards in 2018. In 2020, Melodrama ranked at number 460 on Rolling Stone's revision of their 500 Greatest Albums of All Time list.
