Acts 3 is the third chapter of the Acts of the Apostles in the New Testament of the Christian Bible. The book containing this chapter is anonymous but early Christian tradition affirmed that Luke composed this book as well as the Gospel of Luke. This chapter records the healing of a disabled person by the apostles Peter and John, and Peter's preaching at Solomon's Porch in the Second Temple.

The original text was written in Koine Greek. This chapter is divided into 26 verses.
