The Lao Prime Minister's Cup () is an annual association football tournament in Laos, first established in 2003 to provide a platform for teams outside of Vientiane to compete against those in the Lao Premier League. In addition to encouraging the development of association football across Laos, it is intended to celebrate the National Day of Laos on December 2. It is sponsored by Beerlao and called the "Battle of the Provinces".
Format consists of a qualifying stage for regional teams, usually 3 groups of 4 teams, played at the Savannakhet Stadium in Savannakhet, the Champasak Stadium in Pakse and the Luang Prabang Stadium in Luang Prabang. The winners of these groups then join the top teams from the Lao Premier League, divided into 2 groups with round-robin tournament format. The top two teams then proceed to the semi-final to determine the two teams who will play in the final.
