Olga de Amaral (Colombian, b.1932) is a textile artist known for her large gold- and silver-leaf tapestries. Born in Bogotá, de Amaral studied architecture at the Collegio Mayor de Cundinamarca, and later studied fiber art and textiles at the Cranbrook Academy of Art in Michigan. After returning to Colombia, she became the founding director of the Textiles Department at the Universidad de los Andes.

Her work, which played an important role in the development of Post-War Latin American abstraction, is primarily concerned with color and structure, as well as process and materiality. She creates her works by applying gold and silver leaf and acrylic paint to canvases made of woven silk, cotton, horsehair, or linen. In addition to drawing from personal experience, de Amaral is inspired by the Colombian landscape, adobe houses, pre-Columbian textiles, Indian basket weaving, and the principles of abstract geometry.

In 1973, she was awarded the Guggenheim Fellowship, and, in 2005, she was selected as an Artist Visionary by the Museum of Arts and Design in New York. In 2008, she was honorary co-chair for the benefit of the Multicultural Audience Development Initiative at The Metropolitan Museum of Art in New York. She has exhibited at institutions around the world, including the Musée d’Art Moderne de la Ville de Paris, the Indianapolis Museum of Art, and the Museum of Modern Art in Kyoto, Japan. Her work is part of the permanent collections of the De Young Museum in San Francisco, the Museum Bellerive in Zurich, the Museum of Fine Arts, Houston, The Museum of Modern Art and The Metropolitan Museum of Art in New York, the Art Institute of Chicago, and the National Gallery in Washington, D.C., among others.
