The League of Legends SEA Tour (LST) was a professional League of Legends esports tournament in Southeast Asia that was founded in 2018 by Garena as a replacement for the Garena Premier League (GPL). The competition consisted of teams who qualified through the LST qualifiers of each minor region: Indonesia–Malaysia–Singapore, Philippines, and Thailand. Winners of the LST represented Southeast Asia at the Mid-Season Invitational and World Championship.
It was announced in September 2019 that the LST would be merged with the League of Legends Master Series (Taiwan/Hong Kong/Macau) to create a new professional league for all Garena-affiliated regions (excluding Vietnam), the Pacific Championship Series (PCS).
