The activation cross sections of the alpha-particle-induced reactions on natural gadolinium up to 50 MeV were measured. The stacked foil technique, the activation method and the γ-ray spectrometry were used for the measurement. We determined the experimental production cross sections of ^155,157,159Dy, ^{153,155,156g,160,161}Tb and ¹⁵³Gd. No previous experimental data of ^155,159Dy, and ¹⁵³Gd were found in the literature. The measured values were compared with the previous experimental data and the TENDL-2019 data.
