Zechariah 2 is the second of the 14 chapters in the Book of Zechariah in the Hebrew Bible or the Old Testament of the Christian Bible. This book contains the prophecies attributed to the prophet Zechariah. In the Hebrew Bible it forms part of the Book of the Twelve Minor Prophets. This chapter is a part of a section (so-called "First Zechariah") consisting of Zechariah 1–8. It records the third of eight visions received by the prophet (verses 1–5), followed by an oracle calling the exiles to return to the city where Yahweh is about to dwell and all nations will come (verses 6–13).

The original text was written in the Hebrew language. This chapter is divided into 13 verses in English Bibles. The Hebrew Bible uses different "verse numbering" (see below).

There are some differences in verse numbering of this chapter in English Bibles and Hebrew texts:

This article generally follows the common numbering in Christian English Bible versions, with notes to the numbering in Hebrew Bible versions.

Some early manuscripts containing the text of this chapter in Hebrew are of the Masoretic Text, which includes the Codex Cairensis (from year 895), the Petersburg Codex of the Prophets (916), and Codex Leningradensis (1008).

Fragments containing parts of this chapter were found among the Dead Sea Scrolls, that is, 4Q80 (4QXII^e; 75–50 BCE) with extant verses 6–10 (verses 10–14 in Masoretic verse numbering).

There is also a translation into Koine Greek known as the Septuagint, made in the last few centuries BCE. Extant ancient manuscripts of the Septuagint version include Codex Vaticanus (B; ${\displaystyle {\mathfrak {G}}}$^B; 4th century), Codex Sinaiticus (S; BHK: ${\displaystyle {\mathfrak {G}}}$^S; 4th century), Codex Alexandrinus (A; ${\displaystyle {\mathfrak {G}}}$^A; 5th century) and Codex Marchalianus (Q; ${\displaystyle {\mathfrak {G}}}$^Q; 6th century). Some fragments containing parts of this chapter (a revision of the Septuagint) were found among the Dead Sea Scrolls, i.e., Naḥal Ḥever 8Ḥev1 (8ḤevXII^gr); late 1st century BCE) with extant verses 3-5, 7-8, 12-13 (verses 7–9, 11–12, 16–17 in Masoretic verse numbering).

This section records the third of Zechariah's eight visions, in which he saw a man with a measuring line travelling to Jerusalem to measure the city's length and width. The vision points to the unlimited size of the restored city (cf. Isaiah 49:19–21), assuring the people that God's glory will be in there (cf. Ezekiel 43:1–5; Haggai 2:9). Jerusalem will become "a city without walls". Katrina Larkin notes that "the formerly negative image of a city without walls becomes a positive one". God will protect the people as in the past (Exodus 13:21).
