Geography
Stara Syniava Raion was located in the eastern part of Khmelnytskyi Oblast, corresponding to the modern-day boundaries of the Volhynia and Podolia historical regions.

History
It was first established on March 7, 1923 as part of a full-scale administrative reorganization of the Ukrainian Soviet Socialist Republic.

Subdivisions
At the time of disestablishment, the raion consisted of one hromadas, Stara Syniava settlement hromada with the administration in Stara Syniava.

Stara Syniava Raion was divided in a way that followed the general administrative scheme in Ukraine. Local government was also organized along a similar scheme nationwide. Consequently, raions were subdivided into councils, which were the prime level of administrative division in the country.

Each of the raion's urban localities administered their own councils, often containing a few other villages within its jurisdiction. However, only a handful of rural localities were organized into councils, which also might contain a few villages within its jurisdiction.

Accordingly, the Stara Syniava Raion was divided into:
 * 1 settlement council—made up of the urban-type settlement of Stara Syniava (administrative center)
 * 16 village councils

Overall, the raion had a total of 45 populated localities, consisting of one urban-type settlement, and 44 villages.
