Mieczewo [mjɛˈt͡ʂɛvɔ] is a village in the administrative district of Gmina Mosina, within Poznań County, Greater Poland Voivodeship, in west-central Poland.

According to historical records, in 1510 the parish included Dobiertki, Góra, Czołowo and Ożyczewo, which no longer exists.

In 1614 all the villages became a part of the Bnin parish, and in 1639 the ruined church in Mieczewo was demolished.

In the late 19th century, the village was composed of 38 farms, with 455 inhabitants.

At least 30 people from this village emigrated to Michigan at that time.
