Michael Holbrook Penniman Jr. (born 18 August 1983), known professionally as Mika ( MEE -kə, stylised in all caps), is a singer-songwriter born in Beirut, Lebanon, and raised in Paris and London.

After recording his first extended play, Dodgy Holiday , Mika was predicted to be the number-one breakthrough act of 2007 in an annual BBC poll of music critics, Sound of 2007. Mika released his first full-length studio album, Life in Cartoon Motion , on Island Records in 2007, which has sold more than 8.3 million copies worldwide and helped Mika win a Brit Award—Best British Breakthrough act—and receive a Grammy Award nomination. He topped the UK Singles Chart in January 2007 with "Grace Kelly" and has since gone on to record four more platinum-selling studio albums (most recently My Name is Michael Holbrook released in October 2019), as well as serve as judge/mentor on both the French version of The Voice and the Italian version of X Factor.

Mika also starred for two seasons in his own television variety show in Italy, Stasera Casa Mika , which won the 2017 Rose d'Or Award for Entertainment, and has hosted his own BBC Radio 2 show The Art of Song. In 2022, he co- hosted the Eurovision Song Contest alongside Italian singer Laura Pausini and Italian television presenter Alessandro Cattelan.

In addition to his musical career, Mika has also worked as a visual artist and designer on various projects, among them sunglasses for the Italian eyewear company Lozza, a clothing line for Belgian retailer JBC, pens for the 100th anniversary of Pilot, and (along with his sister Yasmine) three watches for Swiss company Swatch.
