Polyaenus or Polyenus ( ; see ae (æ) vs. e; , "much-praised") was a 2nd-century CE Macedonian author, known best for his ''Stratagems in War'' (), which has been preserved. The ''Suda'' calls him a rhetorician, and Polyaenus himself writes that he was accustomed to plead causes before the Roman emperor. Polyaenus dedicated ''Stratagems in War'' to the two emperors Marcus Aurelius () and Lucius Verus (), while they were engaged in the Roman–Parthian War of 161–166, about 163, at which time he was too old to accompany them in their campaigns.
