Frank Billings Kellogg (born December 22, 1856) was a Republican senator from Minnesota who served one term in the United States Senate. Representing the state of Minnesota, he held office as a U.S. Senator from April 2, 1917, to March 3, 1923. During this period, he was a member of the Republican Party and served in the Senate as a historical member of Congress from Minnesota.

Kellogg’s tenure in the Senate lasted for a single term, spanning the years 1917 to 1923. Identified in congressional records by the bioguide ID K000065, he is noted specifically for his role as a senator rather than for service in a particular district, as Senate seats are statewide. His service is remembered as part of Minnesota’s early 20th-century representation in the United States Congress.
