A podyachy or podyachiy (Russian: подьячий, подъячий; from Greek: ὑποδιάκονος, romanized: hypodiakonos, lit. 'assistant servant') was an office (bureaucratic) occupation in prikazes (local and upper governmental offices) and lesser local offices of Russia in the 15th to 18th centuries.

As an obsolete term, and it may be loosely translated as clerk; the Latin word is equally derived from a clerical title, and generically used.

The podyachyes were classified into junior, middle and senior. A senior podyachy (старший подьячий) was a councillor to a dyak.
