TopNotch is a Dutch record label specializing in hip-hop. The label was founded in 1995, and is run by Vincent Patty. After some commercial success it became allied with Virgin EMI Records, and since 2004 has a marketing and distribution deal with PIAS Entertainment Group. It has expanded into Dutch-language music by singer-songwriters such as Lucky Fonz III, and in 2009 signed a distribution and marketing agreement with Universal Music Group.
