Buzurg Ibn Shahriyar of Ramhormuz (full name بزرگ بن شهریار الرام هرمزي), was allegedly a Muslim traveler, sailor, cartographer and geographer who was born in Khuzistan in Persia. In the year 953 he supposedly completed a collection of narratives from Muslim sailors based in Siraf, Oman, Basra and elsewhere.
