Reeves's father is a Native Hawaiian, Portuguese, English, Scottish, at least 1/16th Chinese and remote Dutch, his mother is English.
Keanu Reeves was born on September 2, 1964, in Beirut, Lebanon, and was raised in Toronto, Canada. His parents, Samuel Nowlin Reeves, a Chinese-Hawaiian geologist, and Patricia, an entertainer, divorced when Keanu was three. Reeves used to move around from one place to another with his mother and had many stepfathers. After his parents’ formal divorce, Reeves and his mother shifted to Sydney, Australia, where she worked as a costume designer. In there his half-sister Kim was born and the three of them again moved to New York, while his father went to live in Hawaii where Reeves visited him until he was 13 years old. He and his dad have no relationship. His father served time in prison. He was paroled after serving two years of a ten-year sentence for selling heroin at Hilo Airport (1992). "I feel like I got my father's blood, and I am not that happy about it," he told Rolling Stone magazine in 2000.
It was a matter of sometime that his mother again married for the second time in New York to director Paul Aaron and they all moved to Toronto with him and attained Canadian citizenship. But only a year after, the couple split and Reeves’ mother married for the third time in 1976 to a rock promoter called Robert Miller and Reeves second half-sister Karina was born. She got divorced again and married for the fourth time in 1994 to a hairdresser called Jack Bond.
All of this emotional instability and geographical vagrancy, Reeves and his sisters were mostly raised by baby-sitters and grandparents. Reeves has said, "My grandmother is Chinese and Hawaiian so I was around Chinese art, furniture, and cuisine when I was growing up." He has also spoken of his English ancestry, mentioning happily watching British comedy shows such as The Two Ronnies during his childhood, and how his mother imparted English manners that he has maintained into adulthood.
Reeves was named after his uncle Henry Keanu Reeves. "Keanu" is a derivation of Reeves' great-great-uncle Keaweaheulu, whose name means "the soft breeze raising" in Hawaiian.
Reeves is entitled to British citizenship through his English mother. He holds Canadian citizenship by naturalization. He grew up as a Canadian and identifies as such, and holds an American green card. Reeves' biological father was born in the United States but Reeves required a green card because he was not eligible to claim automatic citizenship by birth abroad to one United States citizen.
