The Notorious IBE is a three day international Hip Hop dance event in Heerlen, The Netherlands. Unlike many other Hip Hop dance events the IBE is set up like a festival and was first organised in the city of Rotterdam in 1998.

The festival's mission is to gather Hip Hop dance lovers and competitors in a festival setting in where insiders and outsiders of the culture feel at home. Each festival IBE strives to present the latest Hip Hop dance developments and backgrounds through dance battles, shows, workshops, talkshows, art exhibitions and music performances. Every year a number of special programs is organised to highlight the annual festival theme.

The IBE festival program takes places at different locations called "Cyphers" all are located right in the city centre of Heerlen. Heerlen is located in Limburg holland's southernmost province. The Heerlen city region is surrounded by touristic cities such as Valkenburg and Maastricht which are full of hotels, hostels and campings. The festival organisation is committed to help every person visiting the event by offering group arrangements, bus tours from different countries and a low budget accommodation called the IBE Sleepover.
