Sheikh Sulaiman bin Abdulaziz Al Rajhi (Arabic :سليمان بن عبد العزيز الراجحي, born 1929)[1] is a Saudi Arabian corporate figure and billionaire.

A co-founder of the bank, with older brother, Saleh, he is currently the chairman of what is nationally recognized as the Tadawul's most venerable institution.

The Al Rajhi brothers’ business growth and expansion was fed by the flood of migrant workers to Saudi Arabia during the 1970s oil boom.

In 1983, the brothers won permission to open Saudi Arabia’s first Islamic bank, one that would observe religious tenets such as a ban on interest.
