Magnetic measurements of HoAl_{2} are reported. The compound crystallizes in the cubic MgCu_{2}-type crystal structure. HoAl_{2} exhibits two successive magnetic transitions: below T_{c} = 29 K a ferromagnetic order is formed while anomaly at T_{t} = 20 K is related to reorientation of magnetic moment. Near transition temperatures a magnetocaloric effect with magnetic entropy changes -ΔS_{m} equal to 6.3 J/(mol K) at T_{c} and 5.0 J/(mol K) at T_{t} for an external field μ_{0}H = 9 T is observed.
