Hefner died at his home in Holmby Hills, Los Angeles, California, on September 27, 2017, at the age of 91. Before his death he had planned for a cremation and for his ashes to be interred at Westwood Memorial Park in Los Angeles, in the crypt beside Marilyn Monroe. "Spending eternity next to Marilyn is an opportunity too sweet to pass up," Hefner had told the Los Angeles Times in 2009.
