The Second Temple (Hebrew: בֵּית־הַמִּקְדָּשׁ‎ הַשֵּׁנִי‎, romanized: Bēṯ hamMīqdāš hašŠēnī, lit. 'Second House of the Sanctum') was the temple in Jerusalem that replaced Solomon's Temple, which was destroyed during the Babylonian siege of Jerusalem in 587 BCE. It was constructed around 516 BCE and later enhanced by Herod the Great around 18 BCE, consequently also being known as Herod's Temple thereafter. Defining the Second Temple period and standing as a pivotal symbol of Jewish identity, it was the basis and namesake of Second Temple Judaism. The Second Temple served as the chief place of worship, ritual sacrifice (korban), and communal gathering for the Jewish people, among whom it regularly attracted pilgrims for the Three Pilgrimage Festivals: Passover, Shavuot, and Sukkot.

In 539 BCE, the Persian conquest of Babylon enabled the Achaemenid Empire to expand across the Fertile Crescent by annexing the Neo-Babylonian Empire, including the territory of the former Kingdom of Judah, which had been annexed as the Babylonian province of Yehud during the reign of the Babylonian king Nebuchadnezzar II, who concurrently exiled part of Judah's population to Babylon. Following this campaign, the Persian king Cyrus the Great issued the "Edict of Cyrus" (sometimes identified with the Cyrus Cylinder), which is described in the Hebrew Bible as a royal proclamation that authorized and encouraged the repatriation of displaced populations in the region. This event is called the return to Zion in Ezra–Nehemiah, marking the resurgence of Jewish life in what had become the self-governing Persian province of Yehud. The reign of the Persian king Darius the Great saw the completion of the Second Temple, signifying a period of renewed Jewish hope and religious revival. According to the biblical account, the Second Temple was originally a relatively modest structure built under the authority of the Persian-appointed Jewish governor Zerubbabel, who was the grandson of the penultimate Judahite king Jeconiah.

In the 1st century BCE, Herod's efforts to transform the Second Temple resulted in a grand and imposing structure and courtyard, including the large edifices and façades shown in modern models, such as the Holyland Model of Jerusalem in the Israel Museum. The Temple Mount, where both Solomon's Temple and the Second Temple stood, was also significantly expanded, doubling in size to become the ancient world's largest religious sanctuary. The Temple complex was not only a place of worship but also served multiple functions, including being a site for public assemblies. The Sanhedrin, the supreme judicial court, convened in the Temple's Hall of Hewn Stones, and the compound also hosted one of the largest marketplaces in the city.

In 70 CE, at the height of the First Jewish–Roman War, the Second Temple was destroyed by the Roman siege of Jerusalem, resulting in a cataclysmic shift in Jewish history. The loss of the Second Temple prompted the development of Rabbinic Judaism, which remains the mainstream form of Jewish religious practices globally.

The accession of Cyrus the Great of the Achaemenid Empire in 559 BCE made the re-establishment of the city of Jerusalem and the rebuilding of the Temple possible. Some rudimentary ritual sacrifice had continued at the site of the first temple following its destruction. According to the closing verses of the second book of Chronicles and the books of Ezra and Nehemiah, when the Jewish exiles returned to Jerusalem following a decree from Cyrus the Great (Ezra 1:1–4, 2 Chronicles 36:22–23), construction started at the original site of the altar of Solomon's Temple. These events represent the final section in the historical narrative of the Hebrew Bible. The original core of the book of Nehemiah, the first-person memoir, may have been combined with the core of the Book of Ezra around 400 BCE. Further editing probably continued into the Hellenistic era.

Based on the biblical account, after the return from Babylonian captivity, arrangements were immediately made to reorganize the desolated Yehud Province after the demise of the Kingdom of Judah seventy years earlier. The body of pilgrims, forming a band of 42,360, having completed the long and dreary journey of some four months, from the banks of the Euphrates to Jerusalem, were animated in all their proceedings by a strong religious impulse, and therefore one of their first concerns was to restore their ancient house of worship by rebuilding their destroyed Temple.

On the invitation of Zerubbabel, the governor, who showed them a remarkable example of liberality by contributing personally 1,000 golden darics, besides other gifts, the people poured their gifts into the sacred treasury with great enthusiasm. First they erected and dedicated the altar of God on the exact spot where it had formerly stood, and they then cleared away the charred heaps of debris that occupied the site of the old temple; and in the second month of the second year (535 BCE), amid great public excitement and rejoicing, the foundations of the Second Temple were laid. A wide interest was felt in this great movement, although it was regarded with mixed feelings by the spectators.

The Samaritans wanted to help with this work but Zerubbabel and the elders declined such cooperation, feeling that the Jews must build the Temple unaided. Immediately evil reports were spread regarding the Jews. According to Ezra 4:5, the Samaritans sought to "frustrate their purpose" and sent messengers to Ecbatana and Susa, with the result that the work was suspended.
