326 Tamara is a large Main belt asteroid. It is classified as a C-type asteroid and is probably composed of carbonaceous material. It is the largest member and namesake of the Tamara Family, a 264 million year-old sub-family of the collisional Phocaea family.

It was discovered by Johann Palisa on 19 March 1892 in Vienna and is named after Tamar of Georgia. Name was given by Grand Duke George Alexandrovich of Russia. ^[3]
