Rezgiai (formerly ru|Резги, pl|Rezgi, Rezgie) is a village in Kėdainiai district municipality, in Kaunas County, in central Lithuania. According to the 2011 census, the village was uninhabited. It is located from Krakės, from Plinkaigalis, by the Šušvė river and its tributary the Pušynėlis rivulet (with a pond on it). There is a cemetery with a monument to the January Uprising resurgents. Also a lime tree alley of the former manor is still here.
At the end of the 19th century there were three Rezgiai estates by the Šušvė. There was a wooden chapel of St. Eustatius (built in 1759), distillery and water mill. Later there were two estates, one of them belonged to the Jelenskiai, another to the Višnevskiai.
