Kolainiai is a village in Kelmė District Municipality, Lithuania. It is located about southwest from Užventis. According to the 2011 census, it had population of 261.
In 1750, local noble Adamkavičius bequeathed his manor and land with serfs to the Carmelites. He also built a monastery and a church for the monks. In 1797, the monks took over the administration of the Kražiai College, a former Jesuit school. After Tsarist authorities secularized the college in 1817, the Carmelites established their own school in Kolainiai. The school was closed in 1835 after the November Uprising. The monastery itself was closed after the January Uprising of 1863. Russian settlers from Blagoveshchensk ( Amur Oblast) were moved into the monastery; the town became known as Blagoveshchenskoye . The Catholic Church was converted into an Eastern Orthodox church. Catholics reclaimed the church in 1922 after Lithuania declared independence in 1918.
The village had 100 residents in 1861, 364 in 1880, 313 in 1923, 257 in 1957, 295 in 1975, 299 in 1979.
