Punjab has five doabs. The word "doab" means the land between two rivers (do = two, ab = water). The five doabs in Punjab are:

1. Bist Doab (Between the Beas and Sutlej rivers)
2. Bari Doab (Between the Ravi and Beas rivers)
3. Rachna Doab (Between the Ravi and Chenab rivers)
4. Chaj Doab (Between the Chenab and Jhelum rivers)
5. Sindh Sagar Doab (Between the Jhelum and Indus rivers)

These five doabs collectively make Punjab the "Land of Five Rivers" (Panj Ab).
