Nikos Hadjikyriakos-Ghikas (Greek: Νίκος Χατζηκυριάκος–Γκίκας; February 26, 1906 – September 3, 1994), also known as Niko Ghika, was a leading Greek painter, sculptor, engraver, writer and academic. He was a founding member of the Association of Greek Art Critics, AICA-Hellas, International Association of Art Critics.
He studied ancient and Byzantine art as well as folk art due to his adoration for the Greek landscape. During his youth he was exposed in Paris to the avant-garde European artistic trends and he gained recognition as the leading Greek cubist artist.
His aim was to focus on the harmony and purity of Greek art and to deconstruct the Greek landscape and intense natural light into simple geometric shapes and interlocking planes.
His works are featured in the National Gallery (Athens), the Musée d'Art Moderne de la Ville de Paris, the Tate Gallery in London, the Metropolitan Museum of New York and in private collections worldwide.
