Aims.We searched for very high energy (VHE) γ-ray emission from the supernova remnant Cassiopeia A Methods.The shell-type supernova remnant Cassiopeia A was observed with the 17 m MAGIC telescope between July 2006 and January 2007 for a total time of 47 h. Results.The source was detected above an energy of 250 GeV with a significance of 5.2σ and a photon flux above 1 TeV of (7.3 ± $0.7_{\rm stat}$ ± $2.2_{\rm sys})$ $\times$ 10-13 cm-2s-1. The photon spectrum is compatible with a power law dN/dE $\propto$ $E^{-\Gamma}$ with a photon index Γ = 2.3 ± $0.2_{\rm stat}$ ± $0.2_{\rm sys}$. The source is point-like within the angular resolution of the telescope
