Palaioselli (, ) is a settlement in Ioannina regional unit, Epirus, Greece. The village located in a ravine on the right side of the river Vjosa.
The toponym is a compound and comes from the Greek adjective palio and the Slavic loanword in the Greek Epirot dialect selio meaning the 'garden, the farm near the house'. Selio stemming from the Slavic word selo is found in several Slavic languages: Bulgarian selo 'tent, dwelling, field', Serbo-Croatian selo, Slovenian selo 'homestead, dwelling, farm' and Russian selo 'village, ecclesiastical area'. As such, linguist Kostas Oikonomou states linguist Max Vasmer is incorrect in rendering the placename in Slavic as Staro Selo with a translation of the first part.
Palioseli has an Aromanian population and is an Aromanian speaking village. In the early 21st century, elderly people were bilingual in the community language and Greek, whereas younger residents under 40 might have understood the community language but did not use it.
