Jahron Anthony Brathwaite (born July 3, 1993), known professionally as PartyNextDoor (often stylized in all caps), is a Canadian singer, songwriter, and record producer. He was the first artist to sign with Drake's record label OVO Sound, an imprint of Warner Records in 2013. His self-titled debut studio album was released through the label in July that year, and met with critical praise. His second studio album, PartyNextDoor Two (2014), was released the following year and supported by the single "Recognize" (featuring Drake), which received quadruple platinum certification by the Recording Industry Association of America (RIAA). His third album, PartyNextDoor 3 (2016), saw further success and peaked at number three on the Billboard 200, while spawning his first Canadian Hot 100 and Billboard Hot 100 entries with its singles "Come and See Me" (featuring Drake) and "Not Nice". The mixtape, Partymobile (2020), was met with similar commercial success and supported by his highest-charting singles on both charts: "Loyal" (featuring Drake) and "Believe It" (with Rihanna). His fourth album, PartyNextDoor 4 (2024), was met with both commercial and critical reception. His collaborative album with label boss Drake, Some Sexy Songs 4 U (2025) became his first to debut atop both the Billboard Canadian Albums and Billboard 200. Outside of recording, PartyNextDoor has been active in production and songwriting for other artists. He was credited on Rihanna's 2016 single "Work" and DJ Khaled's 2017 single "Wild Thoughts", which peaked at numbers one and two on the Billboard Hot 100, respectively. PartyNextDoor has also contributed to releases by Kanye West, Usher, Christina Aguilera, Post Malone, City Girls, Ne-Yo, Justine Skye, and Jay Park, among others.
