Don Young Day is observed in Alaska every June 9 to honor the late congressman Don Young, who was the longest-serving Republican congressman in U.S. history. Established by the Alaska Legislature and signed into law by Governor Mike Dunleavy in 2023, this day commemorates Young's significant contributions to the state and his 49-year tenure representing Alaska’s at-large congressional district. Born on June 9, 1933, Young moved to Alaska in 1959 and began his political career in 1964. He was known for advocating Alaskan interests, particularly in infrastructure, natural resource development, and support for Native Alaskan communities. Although Don Young Day is not a public holiday, it serves as a day of observance for Alaskans to celebrate his legacy. The observance was initiated on the one-year anniversary of his death on March 18, 2022, and a bill to officially recognize his birthday as Don Young Day was passed in August 2023.
