The Šumera is a river in the Kėdainiai district municipality, Kaunas County, central Lithuania. It flows for 26.2 kilometres (16.3 mi)^[1] and has a basin area of 89 km² (34 sq mi). The river flows into the Obelis (from the right side), a tributary of the Nevėžis, which is in turn a tributary of the Neman.^[3]

The Šumera starts nearby former Dargužiai village and flows mostly southwards through agriculture lands and the Lančiūnava-Šventybrastis Forest. It meets the Obelis in Pašumerys village.

The name Šumera (or Šiumera) is of obscure origin, maybe derived from Lithuanian Germanism šiumas ('foam, decoction').^[4]
