SAKO (PL: System Automatycznego KOdowania[3] - EN: An Automatic Coding System[4]) is a Polish language-based programming language written in years 1959-1960 by a team from ZAM division of Polish Academy of Sciences[1]. Originally developed for the computers XYZ and ZAM-2, in later years also for ZAM-21, ZAM-41 and Mińsk-22.[5]

General features of the SAKO language:
- commands similar to sentences used in natural language
- shortened the time of learning the principles of programming
- easy to use, reduced coding time
- transparent program code, low probability of making a mistake
It had a static address allocation. It was possible to insert code in SAS macro assembler. The compilation proceeded in two stages:
- From SAKO to simplified SAS macro assembler (SAS-W).
- From SAS-W to machine language.
The most characteristic feature of SAKO are Polish commands, e.g. CZYTAJ, SKOCZ DO. Designed primarily for programming numerical calculations.
