Thandiani (literally meaning "very cold") is a hill station in the Galyat area of Pakistan.
Thandiani was originally granted as a lease to some members of the Battye family in British India, who were Christian missionaries and also found in civil and military service, and who produced scions such as Wigram Battye and Quintin Battye. The Battyes subsequently gifted the location to the church authorities, where a sanatorium and various other facilities were set up during the British rule, mostly for the convenience of missionaries, Anglican church personnel and officers stationed at the neighbouring cantonment of Abbottabad. It also contained some private European houses, a camping ground, a small bazaar, and the small seasonal church of St. Xavier in the Wilderness which were occupied only during the summer months.
Thandiani is located in the northeast of Abbottabad District at 34°13'60N 73°22'0E and is about 31 kilometres from Abbottabad in the foothills of the Himalayas. To the east beyond the Kunhar River lies the snow-covered Pir Panjal mountain range of Kashmir. Visible to the north and northeast are the mountains of Kohistan and Kaghan. To the northwest are the snowy ranges of Swat and Chitral. The hills of Thandiani are about 9,000 feet (2,750 m) above sea level. Most of the people residing here belong to the Sadaat (Syed), Qureshi,Abbasi,Jadoon Gujjar, and Karlal tribes. The nearest villages are Bandi Sarara Mara Rehmat Khan, Inderseri, Birnagalli, Chattri, Chamaili, Sialkot, Pattan, Okharela, Dheri, Darer and Kukmang.
