Zechariah 14 is the fourteenth and final chapter of the Book of Zechariah in the Hebrew Bible and the Old Testament of the Christian Bible. The book contains the prophecies during the sixth century BCE attributed to the prophet Zechariah. In the Hebrew Bible it is part of the Book of the Twelve Minor Prophets. This chapter is a part of a section—so-called "Second Zechariah"—consisting of Zechariah 9–14. It continues the theme of chapters 12 and 13 about the "war preceding peace for Jerusalem in the eschatological future'" It is written almost entirely in third-person prophetic discourse, with seven references to "that day".

The original text was written in the Biblical Hebrew. This chapter is divided into 21 verses.

Some early manuscripts containing the text of this chapter in Hebrew are of the Masoretic Text, which includes the Codex Cairensis (895 CE), the Petersburg Codex of the Prophets (916), Aleppo Codex (930), and Codex Leningradensis (1008).

Fragments containing parts of this chapter were found among the Dead Sea Scrolls, that is, 4Q76 (4QXII^a; mid 2nd century BCE) with extant verses 18.

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).

The phrase "that day" occurs seven times in this chapter, having also been used several times in chapters 12 and 13. Biblical scholar Katrina Larkin notes that the phrase has a range of biblical uses, but in Zechariah its meaning is eschatological. Albert Barnes notes that in this chapter, the wording refers back to verse 1, where a literal translation states that "a day is coming, the LORD's". Typically, English translations states that "a day is coming for the LORD".

Sukkot, the Feast of Booths, is singled out in this chapter (verses 16–20) from among the Three Pilgrimage Festivals of Judaism, highlighting its status in the Jewish calendar. The prophet's interest in the fate of the nations who opposed Jerusalem is revealed in the section from verse 12 to verse 19.

This section describes God gathering the nations to lay siege to Jerusalem. When half of the population has been exiled, God comes to deliver the city (2–3), defeating those opposing Jerusalem (verses 12–15).
