North Khorasan in the context of "Khorasan Province"

Eastern Iran includes the provinces North Khorasan, Razavi Khorasan, South Khorasan, and Sistan and Baluchestan some of which share a border with Afghanistan and Pakistan. Some references also count Kerman Province to this region.

Dominated by deserts, this region is characterised by an arid or hyper-arid climate.

Khorasan (Persian: استان خراسان [xoɾɒːˈsɒːn] ; also transcribed as Khurasan, Xorasan and Khorassan), also called Traxiane during Hellenistic and Parthian times, was a province in northeastern Iran until September 2004, when it was divided into three new provinces: North Khorasan, South Khorasan, and Razavi Khorasan.

Khorasan historically referred to a much larger area, comprising the east and the northeast of the Persian Empire. The name Khorāsān is Persian and means "where the sun arrives from". The name was first given to the eastern province of Persia during the Sasanian Empire and was used from the Late Middle Ages in distinction to neighbouring Transoxiana.

The Aladagh Mountains or the Aladagh Range refers to a mountain range situated in the southeastern section of Iran's North Khorasan province, southeast of the Caspian Sea. The range is located 25 kilometres south of Bojnurd, the capital city of North Khorasan. The Aladagh Mountains merge with the Alborz Mountains in the west and then run southeastwards in a northwest-southeast direction. The highest peak of the range is Mount Shahjahan with an elevation of 3,032 metres (9,948 ft). This peak is located about 35 kilometres (22 mi) east of Esfarayen, almost in southeastern part of North Khorasan Province.

The Binalud (Persian: بینالود, pronounced [ˌbiːnɒːˈluːd]) is a mountain range that runs in a northwest-southeast direction between the Nishapur and Mashhad regions in Razavi Khorasan Province in northeastern Iran, to the southeast of the Caspian Sea. Although far from the Aladagh Mountains, which lie to the northwest in the Province of North Khorasan, the Binalud Mountains are located in such a way that both the Aladagh Mountains and the Binalud Range lie approximately in the same arc, curving from the northwest to the southeast. The city of Mashhad is located in the northeastern part of the Binalud Range, and the city of Nishapur or Neyshabur lies on the southwestern section of the range. Situated somewhat to the west of the Binalud Range proper, and with an elevation of 3,211 metres, Mount Binalud is the highest point both of the Binalud Mountains and of Razavi Khorasan Province as a whole.
