Galaxy clusters play a leading role in both present and planned cosmological investigations. They represent the biggest collapsed structure of the Universe, sitting on top of the highest peaks of the dark matter density field. The possibility of modelling their statistical properties as a function of cosmological parameters, combined with the capability of measuring their basic properties, such as the mass, with relative simplicity with respect to other astrophysical objects, makes them optimal tracers of the large-scale structure of the Universe. I will present the cosmological constraints obtained with the largest existing catalogues of galaxy clusters as well the forecasts for future wide surveys, taking as an example the forthcoming European Space Agency mission Euclid.
