Restoration Day in Switzerland refers to holidays celebrated in various cantons to commemorate the restoration of the old order or significant historical events.

One notable example is Geneva's Restoration Day, which occurs on December 31. This day marks the restoration of Geneva's independence and the creation of the Republic of Geneva in 1813 after it was annexed by France during the Napoleonic Wars. The city was occupied by French troops from 1798 until 1813 when they were driven out, and Geneva regained its status as a republic before later joining the Swiss Confederation in 1815.

Traditions on Restoration Day often include official ceremonies, historical reenactments, and public speeches. In Geneva specifically, government buildings may be closed, and there might be various cultural events and exhibitions relating to Geneva’s local history.

Residents often take this day to reflect on their canton's history and spend time with family or participate in community festivities. While not as widely celebrated with pomp as other Swiss national holidays, Restoration Day holds significant historical importance within the cantons that observe it.
