Agathoclea Theotropus was an Indo-Greek queen married to Menander I, who ruled in parts of northern India in the 2nd-century BC as regent for her son Strato I. Born in Bactria, likely to a noble family with some authors such as Tarn alleging she was a daughter of Eucratides, however this is uncertain and Tarn is often criticised by modern authors for casually creating dynastic relationships.
