The Januszajtis putsch of early January 1919 was an unsuccessful coup d'etat in Poland. On 4–5 January 1919, right-wing National Democrats attempted to overthrow the government of Jędrzej Moraczewski and Józef Piłsudski. The coup's leaders included Marian Januszajtis-Żegota and Prince Eustachy Sapieha.

The coup forces succeeded in arresting Moraczewski's government but not Piłsudski. Some military units refused to follow confusing or surprising orders, and eventually the coup ended in some arrests and in a return to the status quo ante. There were no fatalities or significant injuries. In mid-January, right-wing activists were admitted to membership in a coalition government.
