十人委员会（Decemviri，单数：decemvir）乃是一个拉丁文的名词，表示“十人”，它指任何在罗马共和中的十人的委员会。不同型态的十人委员会，包括法律的制定，具备执政官的统治大权（legibus scribundis consulari imperio），控诉的判决（stlitibus iudicandis），献祭的实行（sacris faciundis），以及公共土地（agris dandis adsignandis）的分配。

Decemviri (plural) is a Latin term meaning ten (decem) men (viri). The ancient Romans used it to designate any ten-man commission during the period of the Roman Republic (cf. Triumviri, Three Men). In English it is rendered as decemvirate. Different types of decemvirates included decemviri legibus scribundis consulari imperio (decemviri writing the law with consular power), decemviri litibus iudicandis (decemviri adjudging litigation) decemviri sacris faciundis (decemviri making sacrifices) and the distribution of public lands (agris dandis adsignandis). The singular, decemvir, is used to indicate a member of a decemvirate both in Latin and in English. In English decemvirs is used as a plural for this.
