The intrinsic polarisation parameters P, θ, Q and U of the star μ Cep, in the V spectral region during the period 1979-1989, are presented. The data were obtained from the Belgrade polarimetric observational program. The polarization percentage of the star exhibits change is of about 2.5% during this interval and the position angles change by about 90 degrees. These very large long-term changes of polarization parameters are discussed briefly.
