Bassir (Arabic: بصير) is a village in Hauran, located 630 meters (0.4 miles) above sea level and 51 kilometers (32 mi) southern of Damascus in Syria.

In 1596 Bassir appeared in the Ottoman tax registers as Busayr al-Kubra and was part of the nahiya of Bani Kilab in the Hauran Sanjak.

The villagers paid a fixed tax-rate of 25% on wheat, barley, summer crops, goats and beehives; a total of 2,900 akçe.

As in many other areas of Syria during the time of Ottoman Empire and due to the lack of resources, a notable number of civilians were immigrated to South America including Brazil and Argentina.

[3] It is similar to what is seen in their neighboring sister villages: Khabab, Izra', Tubna, Shaqra that all their current citizens originally immigrated from Salkhad.
