Vipera aspis francisciredi is a venomous subspecies of the European asp[3] endemic to northern and central Italy and adjacent Croatia, Slovenia, and Switzerland.

It also occurs in the Swiss canton of Ticino, south of the Monte Ceneri Pass, but is not found west of nearby Lake Maggiore.

There have been reports of specimens from Ripanj near Belgrade, Jahorin in Bosnia and other parts of "Yugoslavia", but some of these may have been confused with V. berus bosniensis.

[5] Nevertheless, the European Molecular Biology Laboratory (EMBL) describes the range of this subspecies as stretching from southern Switzerland, northern and central Italy, to Slovenia and northwestern Croatia.

[6] The type locality listed by Laurenti (1768) for Vipera Francisci Redi (= V. a. francisciredi) is "Austriaco & Italico" (= Austria and Italy).
