Saudi Exchange (Arabic: تداول السعودية‎) or Tadāwul (Arabic: تداول‎) is a stock exchange in Saudi Arabia. Tadāwul was formed in 2007 as a joint stock company and the sole entity authorized to act as a securities exchange in Saudi Arabia, but trading began in 1954 as an informal financial market. It continued as such with only 14 listed companies through the 1970s and began to acquire some formal status as the Saudi Company for Share Registration in 1980. It is regulated by the Capital Market Authority but has become partially self-regulating since 2018. It lists 203 publicly traded companies (as of 31 December 2020). As of 31 December 2020, its trading hours are 10:00AM to 3:10PM, Sunday to Thursday.

On 26 February 2017, the Saudi Parallel Market (Nomu) was launched as a parallel equity market with lighter listing requirements to provide companies an alternative platform for the public listing.

Tadāwul is completely owned by the Saudi Public Investment Fund.
