使徒教父（英语：Apostolic Fathers），又译为宗徒教父，指基督教使徒以后的初代至二代的教会作家，是生活于一世纪后半至二世纪中叶前的基督教人物。他们之所以被称为使徒教父，是因为他们曾直接接触过，或受教于，耶稣的使徒，或是使徒的门徒。使徒教父这一名称始自十七世纪，起初有五位，后来另加了三位，共八位。

基督教从犹太人的文化中出生。在第一世纪结束时，许多教会已经是以希利尼人为骨干，但是教会的教导与行为模式仍带有浓厚的犹太气息。这些使徒教父是一些带领教会过渡到希腊文化环境的教会领袖。他们的著作是继新约圣经书卷之后，基督教最早的著作。内容很少强调教义，着重的是道德教训。从他们的著作中，我们可以瞥见第二世纪早期的教会生活。

The Apostolic Fathers is a term used to describe a group of Early Christian writings produced in the late 1st century and the first half of the 2nd century. These writings, though popular in Early Christianity, were ultimately not part of the New Testament once it reached its final form. Many of the writings derive from the same time period and geographical location as other works of early Christian literature that did come to be part of the final form of the New Testament, and some of the writings found among the "Apostolic Fathers" seem to have been just as highly regarded as some of the writings (that remained) in the New Testament.
