Iñaki Urdangarín Liebaert, Duke of Palma de Mallorca (1968) is a prominent retired handball player. He is the husband of the Infanta Cristina, Duchess of Palma de Mallorca, the youngest daughter of King Juan Carlos and Queen Sofía of Spain.

In November 2011, Urdangarín was accused of diverting public funds for his own profit through the Nóos institute in the 'Palma Arena' case. Searches were conducted at the Nóos institute by the Spanish Anticorruption bureau, and in December 2011, the Anticorruption bureau confirmed that Urdangarin had been sending important sums of public money to tax havens in Belize and the UK. The Casa del Rey of Spain announced that it had decided that the Duke of Palma was not going to participate in any official Royal Family activity for the foreseeable future, as a result of the Instituto Nóos scandal.
