Kis-Küküllő was an administrative county (comitatus) of the Kingdom of Hungary.

Kis-Küküllő is the Hungarian name for the river Târnava Mică.

The Târnava Mică River flowed through the county.

In 1920, by the Treaty of Trianon, the county became part of the Kingdom of Romania.

Its territory lies in the present Romanian counties Mureș (around Târnăveni), Alba (the south-west), and Sibiu (the south, around Dumbrăveni).
