Zacchaeus, or Zaccheus (Greek: Ζακχαῖος, Zakchaios; Hebrew: זכי, "pure", "innocent"), was a chief tax-collector at Jericho, mentioned only in the Gospel of Luke. A descendant of Abraham, he was an example of Jesus' personal, earthly mission to bring salvation to the lost. Tax collectors were despised as traitors (working for the Roman Empire, not for their Jewish community), and as being corrupt.
Because the lucrative production and export of balsam was centered in Jericho, his position would have carried both importance and wealth. In the account, he arrived before the crowd who were later to meet with Jesus, who was passing through Jericho on his way to Jerusalem. He was short in stature and so was unable to see Jesus through the crowd (Luke 19:3). Zachaeus then ran ahead and climbed a sycamore tree along Jesus' path. When Jesus reached the spot he looked up at the sycamore tree (actually a sycamore-fig ficus sycomorus), addressed Zacchaeus by name, and told him to come down, for he intended to visit his house. The crowd was shocked that Jesus, a religious teacher/prophet, would sully himself by being a guest of a sinner.
Clement of Alexandria refers once to Zacchaeus in a way which could be read as suggesting that some identified him with apostle Matthew or Matthias. Luke told us that Matthias in the beginning was with Jesus since the baptism of John (Acts 1:21-23). John also told us that later many of his disciples turned back and no longer followed him (John 6:60-66). The later Apostolic Constitutions identify "Zacchaeus the Publican" as the first bishop of Caesarea (7.46).
In Eastern Orthodox and Greek-Catholic Churches of Slavic tradition, the Gospel account of Zacchaeus is read on the last Sunday preceding the liturgical preparation for Great Lent, for which reason that Sunday is known as "Zacchaeus Sunday." It is the very first commemoration of a new Paschal cycle. The account was chosen to open the Lenten season because of two exegetical aspects: Jesus' call to Zacchaeus to come down from the tree (symbolizing the divine call to humility), and Zacchaeus' subsequent repentance.
In the Eastern churches of Greek/Byzantine tradition, Zacchaeus Sunday may fall earlier than the Sunday before the Pre-Lenten season.
In Western Christianity, the gospel pericope concerning Zacchaeus is the reading for a Dedication of a Church or its anniversary. In Southern Bavaria, a red banner with white cross may be flown outside a Church on its anniversary, which is consequently called the Zacchaeus flag.
The story of Zacchaeus is used by some  to illustrate the saying of Jesus: "Blessed are the pure of heart, for they shall see God" Matthew 5:8, because the name Zacchaeus means 'pure'. Zacchaeus also becomes a contrast of character with the Rich Young Ruler Luke 18:18-23. Both Zacchaeus and the Rich Young Ruler were wealthy men, but one was self-righteous and would not give up his possessions, while the other gave half his possessions to feed the poor.

- Stromata Book 4 Ch 6 The New Advent Translation says "It is said, therefore, that Zaccheus, or, according to some, Matthew, the chief of the publicans, on hearing that the Lord had deigned to come to him, said, Lord, and if I have taken anything by false accusation, I restore him fourfold;" but the Greek has 18.104.22.168 Ζακχαῖον τοίνυν, οἳ δὲ Ματθίαν φασίν, ἀρχιτελώνην, ἀκηκοότα τοῦ κυρίου καταξιώσαντος πρὸς αὐτὸν γενέσθαι, ἰδοὺ τὰ ἡμίση τῶν ὑπαρχόντων μου δίδωμι ἐλεημοσύνην φάναι, κύριε, καὶ εἴ τινός τι ἐσυκοφάντησα, τετραπλοῦν ἀποδίδωμι. ἐφ' οὗ καὶ ὁ σωτὴρ εἶπεν· can just about be read as "by some said to be Matthias")
