Sinajana (Chamorro: Sinahånña) is the smallest of the nineteen villages in the United States territory of Guam by area.

The village's name may have come from the word "china-jan," cookware used to cook wild yams that once grew in the area.

Didigue is located at the other end of Agana Springs and is accessible by taking a steep single lane road through Afame.
