Katy Perry's Real Name: Katheryn Elizabeth Hudson

Quick answer: Katy Perry's real name is Katheryn Elizabeth Hudson. She was born on October 25, 1984, in Santa Barbara, California. She adopted Katy Perry — using her mother's maiden name — when she moved from Christian music into mainstream pop (Grammy.com; Library of Congress).

Why "Perry" instead of Hudson?

Hudson grew up in a Pentecostal household; her parents, Keith and Mary Hudson, were pastors. She first recorded as a teenage Christian artist under Katheryn Hudson / Katy Hudson. When she shifted to secular pop, another artist already used a similar Hudson name in the marketplace, and she chose Perry, her mom's maiden name, as a clearer pop brand (Grammy.com; major bios). Legal and rights databases still cross-reference Katheryn Elizabeth Hudson.

Chart domination

After the 2008 single "I Kissed a Girl" and album One of the Boys, Perry became a defining late-2000s pop star. Teenage Dream (2010) made history when five of its singles reached No. 1 on the Billboard Hot 100 — matching a Michael Jackson-era record for a single album. Hits include "California Gurls," "Firework," "E.T.," "Last Friday Night (T.G.I.F.)," "Roar" and "Dark Horse." She has sold tens of millions of albums and topped touring grosses with the Witness and Play eras (Billboard).

TV, space and personal life

Perry has been a judge on American Idol, performed the 2015 Super Bowl halftime show, and in 2021 flew on Blue Origin's New Shepard as part of an all-woman crew (widely reported). She was married to Russell Brand (2010–12) and later began a long relationship with actor Orlando Bloom; they have a daughter. She continues to release music and tour into the mid-2020s.

Branding beyond records

Perry's career extends into fragrance, branded tours with elaborate stage design, and long-running TV judging. The Hudson-to-Perry rename is the clearest "real name" hook for searchers: Katheryn Elizabeth Hudson remains the legal identity behind the Katy Perry trademark and writing credits that sometimes still list Hudson.
