We present new spectroscopic observations of the early type, double-lined eclipsing binary V446 Cep. The radial velocities and the photometric data obtained by Hipparcos were analysed for deriving the astrophysical parameters of the components. Masses and radii were determined as Mp=17.94±1.16 M\odot and Rp=8.33±0.29 R\odot, Ms=2.64±0.30 M\odot and Rs=2.13±0.10 R\odot for the components of V446 Cep. Our analyses show that V446 Cep is a detached Algol-type system. Based on the position of the components plotted on the theoretical Hertzsprung-Russell diagram, we estimate that the age of V446 Cep is about 10 Myr, neglecting the effects of mass-loss and mass exchange between the components. Using the UBVJHK magnitudes and interstellar absorption we estimated the mean distance to the system V446 Cep as 1100±62 pc.
