We present here the detection of a planet orbiting around the F6V star HD 33564. The radial velocity measurements, obtained with the ELODIE echelle spectrograph at the Haute-Provence Observatory, show a variation with a period of 388 days. Assuming a primary mass of 1.25 $M_{\odot}$, the best Keplerian fit to the data leads to a minimum mass of 9.1  $M_{\rm Jup}$ for the companion.

Key words: techniques: radial velocities -- stars: binaries: spectroscopic -- stars: early-type -- stars: brown dwarfs -- planetary systems
