Tinn borders the municipality of [[Nore og Uvdal]] (in [[Buskerud|Buskerud county]]) to the north; [[Rollag]] and [[Flesberg]] (also in Buskerud) to the east; [[Notodden]], [[Hjartdal]], and [[Seljord]] to the south, and [[Vinje]] to the west.

Most of Tinn is quite rural. The town of [[Rjukan]] is the largest settlement. It is located in the [[Vestfjorddalen]] valley, through which the [[Måna]] river flows.

Tinn stretches deeply into the [[Hardangervidda]] landscape. One landmark in Tinn is the {{convert|1883|m}} tall mountain [[Gaustatoppen]], which is climbed by 30,000 people each year. On clear days it is possible to see one sixth of Norway from its summit. Other areas include the [[Blefjell]] mountains, with [[Bletoppen]] being the highest mountain in that area and also the [[Vegglifjell]] mountains, with [[Skirveggen]] being the highest mountain in that area.

There are several large lakes in Tinn, including [[Tinnsjå]] and [[Kalhovdfjorden]].
