Tahmasp I (Persian: طهماسب یکم, romanized: Ṭahmāsb or تهماسب یکم Tahmâsb; 22 February 1514 – 14 May 1576) was the second shah of Safavid Iran from 1524 until his death in 1576. He was the eldest son of Shah Ismail I and his principal consort, Tajlu Khanum.

Tahmasp ascended the throne after the death of his father on 23 May 1524. The first years of Tahmasp's reign were marked by civil wars between the Qizilbash leaders until 1532, when he asserted his authority and began an absolute monarchy. He soon faced a long-lasting war with the Ottoman Empire, which was divided into three phases. The Ottoman sultan, Suleiman the Magnificent, tried to install his own candidates on the Safavid throne. The war ended with the Peace of Amasya in 1555, with the Ottomans gaining sovereignty over Iraq, much of Kurdistan, and western Georgia. Tahmasp also had conflicts with the Uzbeks of Bukhara over Khorasan, with them repeatedly raiding Herat. In 1528, at the age of fourteen, he defeated the Uzbeks in the Battle of Jam by using artillery.

Tahmasp was a patron of the arts and was an accomplished painter himself. He built a royal house of arts for painters, calligraphers and poets. Later in his reign, he came to despise poets, shunning many and exiling them to the Mughal court of India. Tahmasp is known for his religious piety and fervent zealotry for the Shia branch of Islam. He bestowed many privileges on the clergy and allowed them to participate in legal and administrative matters. In 1544 he demanded that the fugitive Mughal emperor Humayun convert to Shi'ism in return for military assistance to reclaim his throne in India. Nevertheless, Tahmasp still negotiated alliances with the Christian powers of the Republic of Venice and the Habsburg monarchy who were also rivals of the Ottoman Empire.

His succession was disputed before his death. When Tahmasp died, a civil war followed, leading to the death of most of the royal family. Tahmasp's reign of nearly fifty-two years was the longest of any member of the Safavid dynasty. Although contemporary Western accounts were critical, modern historians describe him as a courageous and able commander who maintained and expanded his father's empire. His reign saw a shift in the Safavid ideological policy; he ended the worshipping of his father as the Messiah by the Turkoman Qizilbash tribes and instead established a public image of a pious and orthodox Shia king. He started a long process followed by his successors to end the Qizilbash influence on Safavid politics, replacing them with the newly introduced 'third force' containing Islamized Georgians and Armenians.
