The 1951 Humboldt State Lumberjacks football team represented Humboldt State College—now known as California State Polytechnic University, Humboldt—as a member of the Far Western Conference (FWC) during the 1951 college football season. Led by first-year head coach Phil Sarboe, the Lumberjacks compiled an overall record of 4–3–1 with a mark of 2–1 in conference play, placing third in the FWC, and outscored their opponents 177–98 for the season. The team played home games at the Redwood Bowl in Arcata, California.
