John Fielder (August 2, 1950 – August 11, 2023) was an American landscape photographer, nature writer, the publisher of over 40 books, and a conservationist. He was nationally known for his landscape photography, scenic calendars (which have been published for over 30 years) and for his many coffee table books and travel guides—including Colorado's best-selling Colorado 1870–2000, in which he matched the same scenes of classic photographs taken in the 19th century by photographer William Henry Jackson.

John Fielder was born on August 2, 1950.^[1] A Washington, DC, native, Fielder moved to Colorado upon graduation from Duke University, where he studied accounting.^[2] After working eight years for department stores, he turned his photography hobby into a profession.^[3]

Fielder married his wife, Virginia, in 1978. The couple became parents of three children.^[4]

Fielder won the Colorado Book Award three times, in 1996, 1997, and 2000.^[5] His photos were published in more than 50 books.^[6]

In January 2023, Fielder released the entirety of his over 5,000 photographs into the public domain, with History Colorado as caretaker.^[7]

Fielder worked to promote the protection of Colorado open space and wild lands. His photography influenced people and legislation, including the Colorado Wilderness Act of 1993, and earned him recognition, including the Sierra Club's Ansel Adams Award in 1993, and in 2011, the Aldo Leopold Foundation's first Achievement Award given to an individual. He was an original governor-appointed member of the lottery-related board of Great Outdoors Colorado, and spoke to thousands of people each year to rally support for land use and environmental issues.

John Fielder died from pancreatic cancer on August 11, 2023, at the age of 73.^[1]
