How many teams finished the 2026 NFL preseason with a 3–0 record?

Four teams finished the 2026 NFL preseason with a 3–0 record: the Baltimore Ravens, Buffalo Bills, Cincinnati Bengals and Los Angeles Rams.

Each of those teams won all three of its standard preseason games. Carolina also won three exhibition games, but the Panthers played four contests because they participated in the Hall of Fame Game and therefore finished 3–1 rather than 3–0.

The four perfect records were the most complete undefeated records possible for teams that played the normal three-game schedule. Arizona also played four games because of the Hall of Fame Game and finished 1–3.

These records describe exhibition performance only. Preseason wins do not count toward regular-season standings, and all four teams began the regular season with a new 0–0 record.
