"Birthday" is a song by American singer Katy Perry from her fourth studio album, Prism (2013). She co-wrote the song with Bonnie McKee and its producers Dr. Luke, Max Martin, and Cirkut. Critics, as well as Perry herself, have compared the track to the music of Prince and Mariah Carey. Through double entendres in the lyrics of "Birthday", Perry makes sexual references while celebrating a partner's birthday. Capitol Records sent the track to mainstream and rhythmic radio on April 21, 2014 as the album's fourth single.

Following the release of Prism, the song entered the single charts of South Korea and France. After being released as an official single, it reached number one on the US Billboard Dance Club Songs chart and the Israeli TV Airplay chart, number three in South Africa, number seven in Canada, number 10 in South Korea, number 17 on the US Billboard Hot 100 chart, and the top 40 in nine additional countries.

A music video for the track was released on April 24, 2014. Primarily recorded with hidden cameras, it features Perry disguised as five different characters in birthday parties and other celebrations. The makeup effects for Perry were designed and created by Tony Gardner. Perry's portrayal of a Jewish character in the video sparked criticism. Jess Glynne covered the song on BBC Radio 1's Live Lounge, and Halsey on SiriusXM.^[1]
