The Feast of Saints Peter and Paul or Solemnity of Saints Peter and Paul is a liturgical feast in honour of the martyrdom in Rome of the apostles Saint Peter and Saint Paul, which is observed on 29 June. The celebration is of ancient origin, the date selected being the anniversary of either their death or the translation of their relics.

For Eastern Orthodox and some Eastern Catholic Christians this feast also marks the end of the Apostles' Fast (which began on the Monday following All Saints' Sunday, i.e., the second Monday after Pentecost). It is considered a day of recommended attendance, whereon one should attend the All-Night Vigil (or at least Vespers) on the eve, and the Divine Liturgy on the morning of the feast (there are, however, no "Days of Obligation" in the Eastern Church). For those who follow the traditional Julian calendar, 29 June falls on the Gregorian calendar date of 12 July.

In the Russian Orthodox tradition, Macarius of Unzha's Miracle of the Moose is said to have occurred during the Apostles' Fast and the Feast of Saints Peter and Paul that followed it.

In the General Roman Calendar, the celebration is a solemnity. In earlier editions, it was ranked as a Double (Tridentine Calendar), Greater Double (e.g., General Roman Calendar of 1954), or First-Class Feast (General Roman Calendar of 1960).
