The Grammy Award for Best Rap Album is an award presented to recording artists for quality albums with rapping at the Grammy Awards, a ceremony that was established in 1958 and originally called the Gramophone Awards.
In 1995, the Academy announced the addition of the award category Best Rap Album. The first award was presented to the group Naughty by Nature at the 38th Grammy Awards the following year.
As of 2015, Eminem holds the record for the most wins in this category, with six. Lauryn Hill is currently the only female artist to win in this category, when she won in 1997 with the Fugees. Jay-Z holds the record for the most nominations, with nine, which resulted in only one win (more like an anti-record).
