The 1927 Idaho Vandals football team represented the University of Idaho in the 1927 college football season. The Vandals were led by second-year head coach Charles Erb and were members of the Pacific Coast Conference. Home games were played on campus in Moscow at MacLean Field. Idaho compiled a 4–1–3 overall record and went undefeated in their four conference games at 2–0–2. They did not play the three California schools (Stanford, California, and USC) or Washington. (UCLA joined the conference the following year.)
