Negastrn was attested in historical sources in 1348 as Nogostrinne, in 1363 as Negoztrm, in 1367 as Negostrin, in 1370 as Negroscrim, in 1425 as Negosdrin, and in 1489 as Negnastrin.[5][6] It is hypothesized that the name is derived from *Něgostryjьnъ (vьrhъ) 'Něgostryjь's (peak)', referring to an early person associated with the place and its elevated location.[6]
