Canton 10 (Croatian: Hercegbosanska županija; Bosnian: Kanton 10; Serbian Cyrillic: Кантон 10) is one of the 10 cantons of the Federation of Bosnia and Herzegovina in Bosnia and Herzegovina. The local government seat is in Livno, while the assembly is in Tomislavgrad.

In Croatian the term županija (county) is used, while in Bosnian and Serbian the term is kanton/кантон. The canton is officially referred by the Federation of Bosnia and Herzegovina as Canton 10/County 10 (Kanton 10 or Županija 10). The local government however refers to it as the Herzeg-Bosnian County (Hercegbosanska županija) and uses that name in the local constitution. This name has been deemed unconstitutional by the Federation's Constitutional Court because the territory of the canton lies entirely outside of the Herzegovina region. Other names used at the national level include North Herzegovina Canton/County (Sjevernohercegovački kanton, Sjevernohercegovačka županija) and Livno Canton (Livanjski kanton), after its capital.

The flag and coat of arms of the canton were the same as the flag and coat of arms of the former Croatian Republic of Herzeg-Bosnia. West Herzegovina Canton was another canton in Bosnia and Herzegovina which also used this flag and coat of arms. However, these symbols were deemed unconstitutional by the Federation Constitutional Court, because "it only represented one group". Defying the court's ruling, the local government continues using these symbols, and the coat of arms is used at plates at the official institutions. Due to the name and symbols dispute, the local police have no official badges.
