Marktrock is a music festival held each year around 15 August, in the heart of the university town of Leuven, Belgium.

The main reasons behind the decision were the raising price of quality artists and groups, the low capacity of the main stage on the Oude Markt, the new and expensive legal regulations each year, the financial risk of open-air festivals, and the organization refused to raise entry tickets for the Oude Markt stage again.

For the 2008 edition, the festival was once again revamped, bringing back the various free stages throughout the city, leaving only the Oude Markt with an entry fee.

The 2009 festival changed its approach once more, ditching both the entry fee and international acts.

It secured additional funding from the city of Leuven on the condition that the festival would focus on local talent.
