救世军（The Salvation Army）是一个于1865年由卜维廉、卜凯赛琳夫妇在英国伦敦成立，以军队形式作为其架构和行政方针，并以基督教作为信仰基本的国际性宗教及慈善公益组织，以街头布道和慈善活动、社会服务著称。其当初成立时所使用的名称是「东伦敦基督教传道部」（East London Christian Mission）。它有一个称呼，为“以爱心代替枪炮的军队”。它的创办人希望能够把福音传给穷困的人，并透过了解穷人们物质及心灵之需要来给予帮助。其国际总部位于英国伦敦，在全世界有几千个分部，分布在117个国家，组织内包括不同年龄层的成员约两百多万人。

The Salvation Army is a Christian church and international charitable organisation structured in a quasi-military fashion. The organisation reports a worldwide membership of over 1.5 million, consisting of soldiers, officers and adherents known as Salvationists. Its founders Catherine and William Booth sought to bring salvation to the poor, destitute and hungry by meeting both their "physical and spiritual needs". It is present in 127 countries, running charity shops, operating shelters for the homeless, and providing personal hygiene products and disaster relief and humanitarian aid to developing countries.
