The 1957San Francisco 49ers season was the team's eighth season in the NFL, and were coming off a 5–6–1 record in 1956, however, they ended the season with a 5 game unbeaten streak.
San Francisco would continue their late season success from the previous year, and would win 5 of their first 6 games and sit in 1st place in the Western Conference. The Niners would then lose 3 in a row on the road to drop to a 5–4–0 record; however, a 3-game winning streak to close out the season would see San Francisco finish with an 8–4–0 record, their best season since 1953. The 49ers finished tied with the Detroit Lions at the top of the Western Conference, which would set up a tie-breaking playoff game at Kezar Stadium, with the winner of the game to face the Cleveland Browns for the NFL Championship. The Lions would win a very close game by a 31–27 score and end the 49ers season and their quest for their first title. 49ers owner Anthony J. (Tony) Morabito died of a heart attack, during the second quarter of the October 27 game against the Chicago Bears at Kezar. The team was notified of his death at halftime, and with tears in their eyes, they went back out and won a come-from-behind victory.
