The siege of Troitsky monastery (Russian: Троицкая осада) was an abortive attempt of the Polish–Lithuanian irregular army (mercenaries) that acted in support of False Dmitry II to capture the Trinity Lavra of St. Sergius, north-east of Moscow. The siege lasted for 16 months, from 23 September 1608 until 12 January 1610.
