Frank Fournier (born 1948) is a French photographer.
Before becoming a photographer, he studied medicine like his father, who was a surgeon.
He moved to New York City and became a staff photographer at Contact Press Images in 1982 after joining the office staff in 1977.
He is best known for his coverage of the 1985 Armero tragedy in Colombia; the Nevado del Ruiz volcano erupted, leading to a mudslide that killed more than 25,000 people.
His portrait of Omayra Sánchez, a 13-year-old girl trapped under the debris of her home, won the 1985 World Press Photo award.
