Kaunissaare is a village in Anija Parish, Harju County, Estonia, south and south-east of the town of Kehra, situated around the Kaunissaare reservoir, on the banks of the Jägala river.

[1] Kaunissaare manor (Latin: Curia nostra Kaunizaar) was first mentioned in 1326 but it disappeared in the following centuries.

Several other buildings that belonged to the manor complex were destroyed and flooded in the beginning of 1980's, when the reservoir was being built on the Jägala river.

[4] The reservoir is part of the Tallinn water supply system and is connected via canals to Pirita, Aavoja and Soodla rivers.
