The 1877–78 season was the seventh season of competitive football in England.

Wanderers became the first club to win the FA Cup three times in a row after beating Royal Engineers 3–1 in this season's final.

It was the fifth time they had won the competition overall.

A disastrous day for England saw them trounced by Scotland seven goals to two.
