Ostrytsia (Ukrainian: Остриця; Romanian: Ostrița) is a village in Hertsa Raion, Chernivtsi Oblast, Ukraine. It hosts the administration of Ostrytsia rural hromada, one of the hromadas of Ukraine,

Until 18 July 2020, Ostrytsia belonged to Hertsa Raion, which was historically a part of the province of Bukovina. The raion was abolished in July 2020 as part of the administrative reform of Ukraine, which reduced the number of raions of Chernivtsi Oblast to three. The area of Hertsa Raion was merged into Chernivtsi Raion. In 2001, 93.73% of the 3,686 inhabitants spoke Romanian (3,455 people) as their native language (93.22% self-declared it Romanian, or 3,436, and 0.52% self-declared it Moldovan, or 19), while 4.96%, or 183 people, spoke Ukrainian. In the Soviet census of 1989, the number of inhabitants who declared themselves Romanians plus Moldovans was 2,965 (324, or 10.05% Romanians plus 2,641 or 81.92% Moldovan) out of 3,224, representing 91.97% of the locality's population, and there were 205 ethnic Ukrainians (6.36%). A large majority of the population switched their declared census identities from Moldovan and Moldovan-speaking to Romanian and Romanian-speaking between the 1989 and 2001 censuses, and the process has continued ever since.
