Ioanna Gika (Greek: Ιωάννα Γκίκα; born 1994) is a Greek-American singer and songwriter.

Gika was born in 1994 in Washington DC. Most recently, Gika’s lyrics were quoted by Booker Prize winner Arundhati Roy in her NY Times best selling book The Ministry Of Utmost Happiness. Gika played in IO Echo which toured throughout the United States and had support slots for Nine Inch Nails, Haim, New Order, and Jon Hopkins amongst others. Ioanna Gika was born in Washington DC from Greek parents, and then she also spent some of her early years in Greece. After many years she returned to her mother’s house back in Greece, during her father’s funeral, where she started writing her first and newly revealed album “Thalassa” (“Sea” in greek), which she also said speaks about the country, but her too.
