Count Jan Nepomucen Potocki (1867–1943) was a Polish nobleman (szlachcic) and social activist who served as a member of the Imperial Council and the Sejm of Galicia.

During the IX term (1897–1900) of the Imperial Council, following the death of Deputy Józef Wiktor, he was elected to replace him on June 7, 1899.

On November 23, 1905, he was elected chairman of the county board in Sanok of the Society of Agricultural Circles [pl], headquartered in Lviv.

To this end, he created the so-called "labor holiday" - an idea according to which people voluntarily dedicated at least one day a year to social work to carry out an important infrastructure project in the vicinity of their place of residence (roads, community centers, chapels, bridges, footbridges, etc.
