Trobelno (, in older sources Trobevno; ) is a small dispersed settlement in the hills above the Tuhinj Valley in the Municipality of Kamnik in the Upper Carniola region of Slovenia.
The origin of the name Trobelno is uncertain. It may derive from the same root as Slovene trebelje (< *trobeljÃÂ ) 'swamp ragwort', referring to the local vegetation. Another possibility is derivation from the Slavic personal name *TrÃÂbelÃÂ. The place name may share the same origin as Trebelno and Trebelno pri PalovÃÂah, based on medieval attestations of those names.
