Glenn L. Jackson (nickname "Mr. Oregon"; April 27, 1902 – June 20, 1980) was an American engineer, influential Oregon transportation planner, and businessman. He made a strong mark on the state as a 20-year member, and later chair, of the Oregon State Highway Commission, later known as the Oregon Transportation Commission.

Jackson was also a trustee of numerous civic and educational organizations, including the Agri-Business Council of Oregon, St. Vincent Medical Foundation, Willamette University, Linfield College Board of Associates, Oregon State University Foundation, Rogue Valley Memorial Hospital, Mercy Flights Inc, Rogue Valley Manor, Foundation of Oregon Research & Education, Indian Festival of Arts Inc. and Columbia River Maritime Museum.

In addition to his corporate and civic roles, Jackson operated several private business ventures in southern Oregon. He owned and operated a cattle ranch, maintaining long-term ties to the region's agricultural community. He also owned a golf club in Medford, which functioned as both a business and a community recreation venue. Jackson further expanded into aviation, owning a regional air charter company that later became part of the consolidation of small Pacific Northwest carriers that formed Horizon Air, linking him to early development of regional commercial aviation in Oregon.

Military Service Jackson served in the United States Army Air Forces during World War II, ultimately attaining the rank of colonel. He was assigned as Executive Officer to General Ira C. Eaker, commander of the Eighth Air Force, during operations in Italy. His service earned him multiple decorations, including the Bronze Star, Legion of Merit, Order of the British Empire, and Crown of Italy.

Public Service and Political Influence Jackson was appointed by Governor Mark Hatfield to the Oregon State Highway Commission in 1959, and served as its chair from 1962 to 1979. Under his leadership, Oregon built more than 700 miles of freeway and over 800 bridges, including major structures such as the Fremont Bridge, Marquam Bridge, and Astoria-Megler Bridge. Jackson also recognized early the limitations of automobile-centric planning and became an advocate for mass transit.

Though a Republican, Jackson supported candidates across party lines and became known as a trusted adviser to multiple Oregon governors, most notably Tom McCall. His ability to navigate political, business, and civic networks earned him the informal title "Mr. Oregon."

Legacy Jackson's influence on Oregon's transportation system remains visible in the state's modern infrastructure. The Interstate 205 bridge over the Columbia River was named the Glenn L. Jackson Memorial Bridge in recognition of his contributions. His leadership in utilities, transportation, and public policy helped shape Oregon's mid-20th-century development, and he is widely regarded as one of the state's most consequential civic figures.

Jackson's daughter, Cynthia Jackson, remained connected to Oregon civic and community life and helped preserve aspects of her father's legacy after his death. According to the Oregon Department of Transportation, she was appointed to the Oregon Transportation Commission in 1987 and was its first female commissioner.

The Glenn Jackson Scholarship Program was established to honor his commitment to public service and civic leadership. Administered through the Oregon Department of Transportation, the program provides annual scholarships to Oregon students pursuing studies related to transportation, engineering, public policy, and community development, continuing Jackson’s legacy of investing in the state’s future leaders.

Jackson leased, then purchased, in 1946, a fashionable Colonial Revival house in Medford that was designed by noted architect Frank Chamberlain Clark. The house, known as the Clark-Jackson House, is listed on the National Register of Historic Places.

Death Jackson died of cancer at the age of 78 on June 20, 1980, in Portland. His passing prompted tributes from political leaders, business executives, and civic organizations across Oregon, reflecting the breadth of his influence on the state's development.
