Ash Sharqiyah (Arabic: الشرقية, English: Eastern Region) was the eastern region (Arabic: منطقة, transliteration: mintaqah) of the Sultanate of Oman. The capital of Ash Sharqiyah is Sur. On 28 October 2011 Ash Sharqiyah Region was split into Ash Sharqiyah North Governorate and Ash Sharqiyah South Governorate.
Ash Sharqiyah Region consisted of eleven provinces (Arabic: ولاية, plural ولايات, transliteration: wilayah, plural wilayat): Sur, Ibra, Al-Mudhaibi, Al Kamil Wal Wafi, Jalan Bani Bu Hassan, Jalan Bani Bu Ali, Wadi Bani Khalid, Dema Wa Thaieen, Bidiya, Al Qabil, and Massirah.
The main cities are Sur and Ibra.
Of particular touristic interest is the Ash Sharqiyah coast, which includes the headlands of Ra's al-Hadd (Arabic: رأس الحدّ) and Ra's al-Ghaima (Arabic: رأس الغيمة). The 42 kilometre stretch of beach between these two places is the most significant nesting ground in the Indian Ocean for green turtles. An estimated 13,000 turtles lay their individual clutches of 80 to 100 eggs annually. Oman's Ministry of Regional Municipalities, Environment and Water administers the site, which is one of the Sultanate's most important natural reserves.
