Edwin Russell (E.R.) Jackman (February 14, 1894 – May 12, 1967) was an American agricultural expert from Oregon. He helped form the Oregon Seed Growers' League and the Oregon Wheat League. In 1964, he joined Reub Long to write The Oregon Desert, which is still a very popular book forty years after its original publication. Jackman's professional papers and photograph collection are maintained in the Oregon State University archives.

Jackman was born on February 14, 1894 in Stillwater, Minnesota. He grew up on his father's 185-acre (0.75 km²) potato, grain, and livestock farm in Flathead County, Montana. From 1913 to 1917, he attended Montana State College in Bozeman (now Montana State University - Bozeman). He then served briefly as an Agricultural Extension Agent in Blaine County, Montana before entering the United States Army in the fall of 1917. He was stationed at Fort Sill, Oklahoma where he served as a First Lieutenant in the Field Artillery. Following World War I, Jackman attended Oregon Agricultural College (now Oregon State University). He majored in Agronomy, receiving a Bachelor of Science in 1921.

After he graduated from Oregon Agricultural College, Jackman was appointed the state's Agricultural Extension Agent for Wasco County, Oregon. As an extension agent, he worked for Oregon State University as part of the United States Department of Agriculture's Federal Cooperative Extension Service (now known as the Cooperative State Research, Education, and Extension Service. In this capacity, he was responsible for advising local farmers and ranchers on modern agricultural techniques, land use, and recommended conservation practices. In 1926, he resigned to enter commercial business, but returned to the Extension Service in 1929. From 1929 until 1953, he served as a farm crop specialist; then from 1953 until his retirement in 1959, he was engaged as a range crop management specialist.
