The singer's father, mother, brother and close friends, along with band members and celebrities — including producer Mark Ronson and media personality Kelly Osbourne, her hair piled beehive-high in an echo of the singer's trademark style — were among several hundred mourners attending the service at Edgwarebury Cemetery in north London.
The Jewish service was led by a rabbi and included prayers in English and Hebrew and reminiscences from Winehouse's father, Mitch Winehouse. The cab driver and jazz singer, who helped foster his daughter's love of music, ended his eulogy with the words "Goodnight, my angel, sleep tight. Mummy and daddy love you ever so much."
It ended with a rendition of Carole King's So Far Away, one of Winehouse's favourite songs.
The family was then due to hold two days of shiva, a Jewish traditional period of mourning.
