Kalki may refer to the following places:

• Kalki, Lubusz Voivodeship (west Poland)
• Kalki, Masovian Voivodeship (east-central Poland)
• Kalki, Warmian-Masurian Voivodeship (north Poland)

In Hinduism, Kalki (Devanagari: ; lit. destroyer of filth) is the tenth and final incarnation of Vishnu in the current Mahayuga, foretold to appear at the end of Kali Yuga, the current epoch. Religious texts called the Puranas foretell that Kalki will be atop a white horse with a drawn blazing sword. He is the harbinger of the end time in Hindu eschatology, after which he will usher in Satya Yuga.
