Saudi Arabia's Foreign Minister, Prince Faisal bin Farhan, will visit Tehran on Saturday, Iran's semi-official Tasnim news agency said on Thursday.
He is set to meet with Iranian officials, Tasnim said.
Iran and Saudi Arabia agreed in March, in a deal brokered by China, to end a diplomatic rift and re-establish relations following years of hostility that had endangered regional stability including in Yemen, Syria and Lebanon.
Iran officially reopened its embassy in Saudi Arabia on June 7.
