Vietnamese National Football Cup (), officially stylized as the National Cup (), is a Vietnamese football competition. It is one of the most important club competitions in Vietnam.
The Vietnamese Cup was first held in 1992. Cảng Sài Gòn was the first cup winner.
Since 2004, entry is open to all teams that competed in the V.League 1 and the V.League 2. The two teams that reach the final were exempt from the preliminary rounds of the next year's competition. The cup winners will qualify to the group stage of ASEAN Club Championship.
V.League 1 teams are allowed to use only one foreign player if they play against a V.League 2 team.
The Vietnamese National Cup winner will also qualify for a single match of the Vietnamese Super Cup against the V.League 1 champion. If one team won both the National Cup and V.League titles, then the runner-up team of the V.League 1 will be qualified for the Super Cup.
