Studeno (pronounced [stuˈdeːnɔ]; German: Brunnsee,[1][2] Gottscheerish: Sheab, Prunnsheab[3]) is a remote abandoned settlement in the Municipality of Kočevje in southern Slovenia.

[5] The name Studeno literally means 'spring', and it and similar forms (e.g., Studenec, Studenci) are relatively common toponyms for places in Slovenia associated with springs.

It is derived from Slavic *studenьcь '(walled) spring', from the adjective *studenъ 'cold'.

[6] The standard German name of the village, Brunnsee, literally means 'lake/pond formed by a spring', probably referring to a spring that was walled to collect water.

[3] The Gottscheerish form Prunnsheab (and the clipped form Sheab) correspond to the standard German: prunn(le) 'spring' + şéa(b) 'lake, sea' (in Karl Schröer's transcription).
