The Allahverdi Khan Bridge (Persian: پل اللهوردی خان), popularly known as Si-o-se-pol (Persian: سیوسهپل, lit. '[the] bridge of thirty-three [spans]'), is the largest of the eleven historical bridges on the Zayanderud, the largest river of the Iranian Plateau, in Isfahan, Iran.
The bridge was built in the early 17th century to serve as both a bridge and a dam. It is a popular recreational gathering place, and is one of the most famous examples of Iran's Safavid architecture.
Si-o-se-pol was built between 1599 and 1602, under the reign of Abbas I, the fifth Safavid king (shah) of Iran. It was constructed under the supervision of Allahverdi Khan Undiladze, the commander-in-chief of the armies, who was of Georgian origin, and was also named after him. The bridge served particularly as a connection between the mansions of the elite, as well as a link to the city's vital Armenian neighborhood of New Julfa.

The bridge has a total length of 297.76 metres (976.9 ft) and a total width of 14.75 metres (48.4 ft). It is a vaulted arch bridge consisting of two superimposed rows of 33 arches, from whence its popular name of Si-o-se-pol comes, and is made of stone. The longest span is about 5.60 metres (18.4 ft). The interior of Si-o-se-pol was originally decorated with paintings, which were often described by travelers as erotic.
