The magnetic properties of (U_{1-x}Dy_{x})Ni_{5} compounds were studied in the temperature range 2-800 K and fields up to 7 T. The compounds having x ≥ 0.2 are magnetically ordered. Above the Curie points, the reciprocal susceptibilities follow a modified Curie-Weiss behaviour. UNi_{5} is a paramagnet. A peak in the temperature dependence of the magnetic susceptibility is evidenced at T ≈ 20 K. For T > 140 K the UNi_{5} susceptibility is temperature independent.
