Trdobojci (pronounced [təɾdɔˈboːi̯tsi]; German: Terdoboitzen[2]) is a settlement in the Haloze Hills in the Municipality of Videm in eastern Slovenia.

It is believed to be a plural demonym (via *Tvьrdobǫd-j-ьci) based on the Slavic personal name *Tvьrdobǫdъ, a clipped form of the older *Tvьrdobǫd-je (selo) 'Tvьrdobǫdъ's village'.

[4][5] The first element of the compound name, tvьrd, means 'hard',[6] and the second, bǫdъ, is an imperative of the verb biti;[7] the name Tvьrdobǫdъ thus meant 'be hard'.
