Alexander Tukhachevsky (; 1793-1831) was a Russian military officer and a Colonel of Imperial Russian Army. A commanding officer of the (14th) Olonets Infantry Regiment, he took part in the Polish-Russian War of 1830 and was killed in the battle of Warsaw (1831). Ironically, his great-grandson Mikhail Tukhachevsky was defeated at the gates of Warsaw almost a century later.
