Acts 8 is the eighth chapter of the Acts of the Apostles in the New Testament of the Christian Bible. It records the burial of Stephen, the beginnings of Christian persecution, the spread of the Gospel of Jesus Christ to the people of Samaria and the conversion of an Ethiopian official. The book containing this chapter is anonymous, but early Christian tradition uniformly affirmed that Luke composed this book as well as the Gospel of Luke. Parts of this chapter (verses 5-13 and 26-40) may have been drawn from an earlier "Philip cycle of stories" used by Luke in assembling his material.

The original text was written in Koine Greek. This chapter is divided into 40 verses.

Some early manuscripts containing the text of this chapter are:

This chapter mentions the following places:

The writer of Acts introduces Saul, later the Apostle Paul, as an active witness of Stephen's death in Acts 7:58, and confirmed his approval in Acts 8:1a. Reuben Torrey, in his Treasury of Scripture Knowledge, suggests that this clause [i.e. verse 8:1a] "evidently belongs to the conclusion of the previous chapter".

The narrative here is focused around two geographical poles: Jerusalem, where the apostles stay (verses 1b, 14) and the "countryside of Judea and Samaria", where the rest of the church is "scattered" (verse 1b), with unnamed disciples continuing the apostles' task of preaching the gospel (verse 4), as the church history moves on to the middle stage of the apostolic commission in Acts 1:8 The story of church's expansion is interwoven with the record of Stephen's burial (verse 2) and the hint of Saul (later "Paul the apostle") future as a zealous instigator of the persecution, indicating that the community most affected by the wave of persecution to follow was the one to which both Stephen and Saul belonged, the 'synagogues of diaspora origin' (8:5–13), because by the time of Acts 9:26 a group of 'disciples' is still in Jerusalem alongside the apostles.

Heinrich Meyer observes a "double contrast": firstly, that "in spite of the outbreak of persecution which took place on that day, the dead body of the martyr was nevertheless honoured by pious Jews"; and secondly, in verse 3, Saul's persecuting zeal is contrasted with this piety. In the Greek word συγκομίζειν (synekomisan, they carried together), the prefix syn- generally means "with", or "together", suggesting that the men carried Stephen's body away together, but Meyer also emphasises that his body was placed with other dead bodies at a burial-place.

While the apostles remain in Jerusalem, "unnamed disciples exploit their scattered condition to spread the gospel".
