Nena Saguil (b. 1914, d. 1994) is a pioneer for Filipino abstract art as seen in her notable works: Power Room (1953), Abstract (1961), Landscapes of the Mind (1969), and Illumination II (1977). Her works often centered around geometric shapes symbolizing the universe at large or at a microscopic level, reflecting her interest in mysticism. Her portfolio is often categorized into the Manila works, which were about her homeland, and the Paris works, where she experimented with cubism, impressionism and surrealism.

Saguil attended the University of Philippines School of Fine Arts where she graduated with an Award of Excellence. In 1954, Saguil received the Walter Damrosch Scholarship, allowing her to study abstract and modern art at the Institute of Spanish Culture in Spain. She then studied at the School of American Arts in Paris and held her first solo art exhibit at Galerie Raymond Creuze. Throughout her life, Saguil exhibited paintings across Europe, Asia, and the Americas. In 1974, she was declared as part of the Twelve Outstanding Overseas Filipinos. In 2006, she was awarded the Presidential Medal of Merit. Her works continued to be displayed at the Lopez Museum, Cultural Center of the Philippines, and the Ateneo Art Gallery.
