Irena Natalia Sawicka (born 20 September 1944, in Warsaw) is a Polish linguist, Balkanologist, and Slavicist with significant interest in Albanology.
In 1972, she obtained her doctoral degree with a dissertation on the structure of consonant clusters in Slavic languages, under the supervision of Janusz Siatkowski.
In 1978, she obtained her habilitation degree at the University of Warsaw with a dissertation titled "Issues of Nominal Predication on the Example of the Serbo-Croatian Language."
Within this university, she also taught Albanian, qualifying some of today's most distinguished Polish Balkanists in Albanology.
