Kalba (Arabic: كلباء) is a city in the United Arab Emirates. It is an exclave of the emirate of Sharjah lying on the Gulf of Oman coast north of Oman and south of the emirate of Fujairah. Khor Kalba (Kalba Creek), a mangrove swamp, is located further south of the town. The town was captured by the Portuguese Empire in the 16th century and was referred to as Chalba. It was an independent member of the Trucial States of the Coast of Oman from 1903 to 1952.
Khor Kalba is accessible by three roads. The first merges after Wadi al-Haloo (وادي الحلو) tunnel with Maliha Road (شارع مليحة) which finally leads to the Sharjah-Kalba Road (90 km) from Sharjah International Airport. There is also the Fujairah-Kalba road (8 km). The Khor Kalba road extends until the border with Oman, and is one of the exit–entry points between the UAE and Oman.
The key tribes that live in Kalba are al-Zaabi, Al-Marashdah and al-Bloushi.
