Dobrna (, Neuhaus ) is a settlement in Slovenia. It is the seat of the Municipality of Dobrna. It is best known for its spa. It lies north of Celje and east of Velenje in an area that is part of the traditional region of Styria. The municipality is now included in the Savinja Statistical Region.
The name Dobrna is probably derived from the Slavic nickname *Dobrъ, referring to an early inhabitant of the place, therefore originally meaning 'Dobrъ's village'. Another possibility is derivation from the common noun *dǫbrъ 'deciduous or oak forest', in turn derived from *dǫbъ 'deciduous tree, oak', referring to the local vegetation.
