Gentleman (born Tilmann Otto, 1975 in Osnabrück, Germany) is a Reggae musician of German descent.

Gentleman resides in Cologne, but sometimes names Jamaica as his home away from home. He is the son of a Lutheran pastor. He is a father of two children, Samuel and Tamica, and is currently dating Tamika, a background singer of the Far East Band, which accompanied him on his first concert tour of Germany in 2002.

He has been traveling to Jamaica regularly since he was 16. Legend has it that he became hooked on his brother's Reggae records and thus wanted to get to know Jamaica first-hand. The island has become a second home for him. In the meantime Gentleman is also regarded as a popular reggae artist in Jamaica as well, which he regards as an honor, being a European. His career began with the collaboration of the band Freundeskreis which produced the song "Tabula Rasa." After beginning his career as a Deejay his music oriented itself on the classic form of the reggae genre, like that of Bob Marley. He sings mainly in English or rather Patois (Jamaican-Creole). With songs like "Send A Prayer" Gentleman expresses his deep belief in God, whereby he adheres to no religion. His album Confidence climbed to number 1 on the German album charts in 2004.

In 1999, Gentleman released his first album Trodin on and in 2002, his 2nd longplayer Journey to Jah. His album Confidence climbed to number 1 on the German album charts in 2004.
