41 (commonly pronounced as "four-one") is an American hip hop group founded in 2022 in Brooklyn. It consists of rappers Kyle Richh, Jenn Carter, and TaTa, who first began recording music together on BandLab during the COVID-19 pandemic before releasing their debut single, "41 Cypher", in early 2022.

In 2022, 41 signed to Republic Records and released the controversial single "Notti Bop", a diss track against rapper Notti Osama after he was fatally stabbed at 14 years old, which went viral on TikTok and YouTube for its associated dance trend parodying his stabbing. Their 2023 single "Bent", released as the lead single from their debut extended play, 41 World: Not the Album (2023), became their most successful song and charted on the Billboard Bubbling Under Hot 100 chart.
