Alexander McDonald (American politician)

Alexander McDonald (1832 – December 13, 1872) was an American businessman and politician who served as a Republican United States Senator from Arkansas from 1868 to 1871.

Born in Scotland, McDonald emigrated to the United States and became a successful businessman, primarily involved in railroad construction and mining. He established himself in Little Rock, Arkansas, following the Civil War.

During Reconstruction, McDonald played a significant role in Arkansas politics. He was elected to the U.S. Senate in 1868 as part of the state's readmission to the Union. His election, and subsequent tenure, were marked by controversy and allegations of corruption. He was accused of using his influence to enrich himself through railroad deals and land speculation.

McDonald served a partial term, his Senate seat becoming vacant on March 3, 1871. He did not seek reelection.

Following his departure from the Senate, McDonald continued his business pursuits. He died in 1872 and is buried in Mount Holly Cemetery in Little Rock. His career remains a controversial chapter in Arkansas's Reconstruction history, reflecting the political and economic complexities of the era.
