女童军（英语：Girl Guides, Girl Scouts）是童军运动当中，从创办到现在，给予女性青少年的组织。这个运动在20世纪早期，为童军运动的一部份。女性青少年于1907年被引入到童军运动当中。在全球各地，女童军运动以不同的方式进行。在某些地方，女性青少年有可能会直接加入童军组织，但部分地方认为单一女性童军组织则是比较好的选择。在其他地方，女童军组织最先发展，后来开放给男性青少年加入，或是直接与男性童军组织合并。在其他方面，混合性别的童军团最先成立，后来部分童军团会发生分裂。同样地，女童军在英文的名称，则会在不同地方、不同时间被使用到，童军团的性质也会随之改变。

Girl Guides and Girl Scouts are a movement similar to Scouting originally, and still largely, for girls and women only. It evolved from 1908 with girls wishing to take part in the Scout Movement.

In different places around the world, the movement developed in diverse ways. In some places, girls joined or attempted to join Scouting organisations. In other places, girls' groups were started, some of them later to open up to boys or merge with boys' organisations. In other instances, mixed groups were formed, sometimes to later split. In the same way, the name Girl Guide or Girl Scout has been used by groups at different times and in different places, with some groups changing from one to another.
