The International 2019 是valve官方举办的第九次国际邀请赛，它在中国上海梅赛德斯-奔驰体育馆举办，这也是在亚洲首次举办。比赛在2019年7月3日，公开资格赛开始，并于2019年8月25日总决赛。最终OG 战队以 3-1 战胜 2017年冠军 Team Liquid 战队，成为历史上唯一一个获得两次冠军的队伍。
2019年国际邀请赛奖金总额超过了3430万美元，是电子竞技有史以来奖金数目最大的赛事，打破了Fortnite世界杯在2019年短暂的3000万美元奖金记录。在赛事期间，valve发行了几个游戏内收费项目，包括The International 2019 Battle Pass——勇士令状（玩家俗称小本子）, 线上锦标赛门票，与大量活动绑定在一起的功能包，饰品宝瓶等。2019年是国际锦标赛第五年，每年刷新前一年的记录。同时这一年也是唯一一次有非dota2比赛打破记录的一年(Fortnite)，尽管时间很短。
The International 2019 became the third consecutive event won by a European team. The event also saw several new records being set, and some old records being broken. OG's back-to-back victory is the first-ever in the event's history. Their win also made Europe the region with the most tournament wins, with 4 titles. The team also became the first one to return to the Grand Finals, and win a second time, with the original champion roster. Natus Vincere, Newbee and Team Liquid had experienced roster changes before they reached the Grand Finals again. OG also became the first champion since Natus Vincere to make it to the Grand Finals the following year.
Team Liquid became the first team to run through the entire Lower Bracket, with the most number of series won during the Main Stage. Their victory against PSG.LGD in the Lower Bracket final meant that two previous champions would meet in the Grand Finals, killing the chances of a new team winning the championship. The International 2019 saw an increase in the number of previous champions attending the event. Natus Vincere and Alliance came back after two years without qualifying. Only two champions did not make it: 2012 winners Invictus Gaming, who fell during the regional qualifiers, and 2016 winners Wings Gaming, who disbanded shortly after winning the championship.
