Ricardo Antonio Olea () is a Chilean American who was a research mathematical statistician with the United States Geological Survey (2006–21). Previously, he spent most of his career with the National Oil Company of Chile (ENAP) in Punta Arenas and Santiago, and with the Kansas Geological Survey in Lawrence. He received the William Christian Krumbein Medal in 2004 from the International Association for Mathematical Geosciences. He served as Secretary-General (1992−1996) and President (1996–2000) for the International Association for Mathematical Geosciences;Officers and Members of Executive Committee , IAMG, retrieved 2015-04-22. and Secretary General (2019–21) of the Compositional Data Association.
