She began her career as a child actress, starring on the children's television series Barney & Friends (2002–2004). Gomez rose to prominence and emerged as a teen idol, for her leading role as Alex Russo on the Disney Channel sitcom Wizards of Waverly Place (2007–2012). As a recording artist, she signed with Hollywood Records in 2008 and formed the pop rock band Selena Gomez & the Scene. With three studio albums and seven singles, each of the band's releases have received gold certifications or higher by the RIAA.

Further pursuing a career as a soloist, Gomez found continued success with her solo studio albums, as each debuted atop the US Billboard 200. Her EDM-inspired debut, Stars Dance (2013) yielded the international top-ten single "Come & Get It". Desiring more artistic control, Gomez signed with Interscope Records to release the electropop set Revival (2015), supported by the top-ten singles "Good for You", "Same Old Love", and "Hands to Myself". Its follow-up, Rare (2020), topped the charts in various countries, and was led by Gomez's first US Billboard Hot 100 number-one single "Lose You to Love Me". She forayed into Spanish-language music with the EP Revelación (2021), which earned her Grammy and Latin Grammy Award nominations. Gomez has also released various collaborative singles, including "We Don't Talk Anymore", "It Ain't Me", "Wolves", "Taki Taki", and "Calm Down (Remix)"; the latter became the most commercially successful afrobeats song of all time and the best-selling collaboration of 2023 globally.

Gomez has starred in many films, including Another Cinderella Story (2008), Ramona and Beezus (2010), Monte Carlo (2011), Spring Breakers (2012), The Fundamentals of Caring (2016), The Dead Don't Die (2019), A Rainy Day in New York (2019), and Emilia Pérez (2024).
