The flag of the Turkish Republic of Northern Cyprus (Turkish: Kuzey Kıbrıs Türk Cumhuriyeti bayrağı) is based on the flag of Turkey with the colors reversed and two horizontal red stripes added at the top and bottom. It was the result of a competition to find a new representative flag for the TRNC. The local use of the Turkish flag is somewhat similar to the use of the Greek flag in the rest of the island.
In 2010 the Greek Cypriot side officially complained about the flag to the EU Commission, framed as an environmental hazard because of toxic materials used to trans-impose it into the mountain side that are liable to leakage. It is also considered by Greek Cypriots as offensive not only to the environment but also their own community and as an act of provocation.
