Iolanda Costa (Portuguese pronunciation: [juˈlɐ̃dɐ ˈkɔʃtɐ]; born 4 November 1994), known mononymously as Iolanda (stylized in all lowercase), is a Portuguese singer and songwriter. She became known for her participation in the first season of the program Uma canção para ti, broadcast by TVI in December 2008.

Iolanda was born in 1994 in Figueira da Foz, but she moved to Pombal as a child. From an early age she revealed a great passion for music, and her vocation did not go unnoticed by her parents, who sent her to study music at Tecnimúsica, a school in Pombal, and later at the Conservatory. At 17 she moved to Lisbon where she graduated in Communication Sciences from ISCSP. She tried performing in bars and national talent competitions as a gateway, then moved to London, where she studied songwriting at the British and Irish Institute of Modern Music, at the University of Sussex.
