卢森尼亚人，与鲁塞尼亚人经常混同，是斯拉夫人的一支。以卢森尼亚语为母语。目前卢森尼亚人的数量大约有55,000人。他们大部分居住罗马尼亚、斯洛伐克和乌克兰等国。有人认为卢森尼亚人不属于东斯拉夫人，也有人认为卢森尼亚人只是乌克兰人的一支。大部分卢森尼亚人信奉东正教。但卢森尼亚（Rusynia）一词的词根却跟俄罗斯（Russia）一词的词根同出于罗斯（rus）一词，可见东斯拉夫民族间的历史渊源。

Rusyns, also known as Carpatho-Rusyns or Ruthenes (Rusyn: Русины Rusyny; also sometimes referred to as Carpatho-Russians or Rusnaks), are a primarily diasporic ethnic group who speak an East Slavic language, known as Rusyn. Carpatho-Rusyns descend from Ruthenians who did not adopt the use of the ethnonym "Ukrainian" in the early 20th century. The use of the term Rusyn was prohibited by some governments, as seen after 1945 in Soviet Transcarpathia, communist Poland, and Czechoslovakia.
