Speaking after a meeting with US Secretary of State John Kerry, Foreign Minister Adel al-Jubeir said any operation would be US-led but that Saudi Arabia would play a leading role.
"The United States government was very supportive and very positive about the kingdom's readiness to provide special forces to the operation in Syria, should the international coalition make a decision to do so," he told reporters.
"So the kingdom will be part of it," he said. "That support came from the White House, it came from the State Department, it was natural for Secretary Kerry to support such a decision."
The United States has publicly confirmed that it has sent a small number of special operations forces to eastern Syria to help local militias fight the Islamic State group.
But debate continues in Washington about the advisability and final size of a possible larger ground operation against the hardline group.
