Dutch rap group from Amsterdam-Bijlmer, North Holland, the Netherlands.

Members include Hydroboy, MocroManiac and RQS, rapping in Dutch. In 2011 the group released their first mix-tape "Hindabuilding" on Rotjoch's Mucho Dinero imprint, with the title track becoming a club hit in the Netherlands. In 2012 Hydroboy was arrested and sentenced to one year in jail, with MocroManiac and RQS performing at the Noorderslag 2013 without him. In 2013 RQS left the group, and Hydro and Mocro released two digital singles, namely "Tot Ik Niet Meer Kan" and "Kill De Bitch" ahead of "Hindabuilding Vol.2". The following year the two parted ways, resulting in the end of Hydroboyz as a group.
