'''Katheryn Elizabeth Hudson''' ({{lahirmati||25|10|1984}}), dikenal secara profesional sebagai '''Katy Perry''', adalah seorang penyanyi, penulis lagu dan juri televisi berkebangsaan Amerika Serikat. Setelah bernyanyi di gereja di masa kecilnya, dia mengejar karier di musik religi ketika remaja. Perry dikontrak oleh Red Hill Records dan merilis album debut studionya ''Katy Hudson'' yang merupakan nama aslinya pada tahun 2001, akan tetapi secara komersial tidak sukses. Dia pindah ke [[Los Angeles]] pada tahun berikutnya untuk mengejar karier di musik sekuler setelah Red Hill berhenti beroperasi dan kemudian dia bekerja bersama para produser seperti Glen Ballard, Dr. Luke, dan Max Martin. Setelah mengambil nama panggung Katy Perry dan dikeluarkan oleh The Island Def Jam Music Group dan [[Columbia Records]], dia menandatangani kontrak rekaman bersama [[Capitol Records]] pada April 2007.

Perry mendapat ketenaran pada tahun 2008 dengan rilis album keduanya, sebuah rekaman [[pop rock]] berjudul ''[[One of the Boys]]'', dan single-nya "[[I Kissed a Girl]]" dan "[[Hot n Cold]]". Lagu ini juga menimbulkan kontroversi atas tema seksualitasnya. Album ketiganya, ''[[Teenage Dream (album Katy Perry)|Teenage Dream]]'' (2010), campuran dari [[disko]], dan merupakan album pertamanya yang memuncaki [[Billboard 200|''Billboard'' 200]] AS. Album ini memuncaki [[Billboard Hot 100|''Billboard'' Hot 100]] AS dengan single "[[California Gurls]]", "[[Teenage Dream (lagu)|Teenage Dream]]", "[[Firework]]", "[[E.T.]]", dan "[[Last Friday Night (T.G.I.F.)]]" dan "The One That Got Away" berada di nomor 3 di tangga lagu ini. Album ini menjadi album pertama oleh seorang artis wanita yang menghasilkan lima lagu nomor satu di AS, dan kedua secara keseluruhan setelah album [[Michael Jackson]] berjudul ''Bad''. Pada bulan Maret 2012, dia mendaur ulang album ini sebagai ''Teenage Dream: The Complete Confection'', yang menghasilkan lagu "[[Part of Me (lagu Katy Perry)|Part of Me]]" dan "[[Wide Awake (lagu Katy Perry)|Wide Awake]]". Album keempatnya, ''Prism'' (2013), merupakan album keduanya yang memuncaki tangga lagu AS. Album ini terinspirasi oleh pop dan dansa, dan dia menjadi artis pertama dengan beberapa video yang mencapai satu miliar pengunjung di [[Vevo]] dengan video dari lagu yang terdapat di album ini seperti "[[Roar (lagu)|Roar]]" dan "Dark Horse". Album kelimanya, ''Witness'' (2017), memasukkan unsur [[electropop]] dan menjadi album ketiganya yang berada di nomor satu di AS. Single tersukses album ini, "Chained to the Rhythm", memecahkan rekor [[Spotify]] sebagai lagu dari artis wanita yang paling banyak didengar daring kurang dari 24 jam dari perilisannya pada waktu itu.

Pada (2020) Katy akhirnya merilis album keenamnya, ''[[Smile|(album)Smile]]'' Setelah rehat selama 3 tahun tidak membuat album. Album ini menjadi album pertama Katy yang hanya menduduki nomor lima di AS, dan album dengan penjualan terendah selama karir bermusiknya.

Perry telah menerima [[Daftar penghargaan dan nominasi yang diterima oleh Katy Perry|banyak penghargaan]], termasuk empat [[Guinness World Records]], lima [[American Music Award]]s, sebuah [[Brit Awards|Brit Award]], dan sebuah [[Juno Award]], dan masuk di daftar tahunan wanita dengan penghasilan tertinggi di musik oleh ''[[Forbes]]'' dari tahun 2011–2018. Pada tahun 2016, kekayaannya diperkirakan mencapai  $125 juta. Dia merupakan salah satu dari artis musik dengan penjualan terlaris sepanjang masa, telah menjual lebih dari 40 juta album dan lebih dari 100 juta rekaman secara global selama kariernya. Sementara itu, di industri film, dia merilis film dokumenter otobiografi berjudul ''[[Katy Perry: Part of Me]]'' pada tahun 2012, dan mengisi suara karakter Smurfette di film tahun 2011 ''[[The Smurfs (film)|The Smurfs]]'' dan [[The Smurfs 2|lanjutannya]] pada tahun 2013. Perry juga mulai menjadi juri di ''[[American Idol]]'' pada tahun 2018.
