Bilma is an oasis town and commune in north east Niger with, as of the 2012 census, a total population of 4,016 people.

It is known for its gardens, for salt and natron production through evaporation ponds,[2] date cultivation, and as the destination of one of the last Saharan caravan routes (the Azalai, from Agadez).

Average high temperatures in "winter" months surpass 27 °C (81 °F), and exceed 40 °C (104 °F) from April to September inclusively, peaking at 44 °C (111 °F) in June.

After independence, the isolation of Bilma made it the destination for disgraced officials under the authoritarian regime of Seyni Kountché, and a prison was built there by the government.

In 1989, UTA Flight 772 crashed into the desert near the town after a bomb exploded on board, killing all 170 people aboard.
