Prince Joachim, 28, travelled from Belgium to Spain for an internship on 26 May, but went to a party two days later in the southern city of Córdoba.
Spanish reports suggest the prince, a nephew of Belgium's King Philippe, was among 27 people at the party.
Córdoba's lockdown rules permit no more than 15 people at gatherings.
Spanish police have launched an investigation into the party. Those found to have flouted lockdown rules could be fined up to €10,000 (£9,000; $11,100)
