In April, Erdogan went to Saudi Arabia after a months-long drive to mend relations between the regional powers.
He held one-on-one talks with Prince Mohammed while there, raising the possibility of Saudi investments that could help relieve Türkiye's beleaguered economy.
Erdogan said last week he and Prince Mohammed, Riyadh's de facto leader, would discuss "to what much higher level" they can take ties during talks in Ankara.
The visit is expected to bring "a full normalisation and a restoration of the pre-crisis period," a senior Turkish official told the media on condition of anonymity. "A new era will begin."
The official said negotiations on a possible currency swap line — which could help restore Türkiye's diminished foreign reserves — were not moving "as fast as desired" and will be discussed privately between Erdogan and Prince Mohammed.
Agreements on energy, economy and security would be signed during Prince Mohammed's visit, while a plan was also in the works for Saudi funds to enter capital markets in Türkiye, the person added.
Prince Mohammed is on his first tour outside the Gulf region in over three years including a visit to Jordan.
