Hpa-an (Burmese: ဘားအံမြို့, [pʰə ʔàɰ̃ mjo̰]; Pwo Eastern Karen: ဍုံထ်ုအင်; S'gaw Karen: ဖၣ်အၣ်ဝ့ၢ်ဖိ, also spelled Pa-an) is the capital and largest city of Kayin State (Karen State), Myanmar (Burma). The population of Hpa-an as of the 2014 census was 421,575. Most of the people in Hpa-an are of the Karen ethnic group.

Legend has it that Hpa-An was created by the dragon king and the frog king. King Mandu (မဏ္ဍုဖားမင်းကြီး), a giant frog lived the top of the Mount Hpan Pu. One day, while out searching for food, he saw a large magic ruby with an emerald club placed on the throne in the foot cave of Mount Hpan Pu, and the frog king thought the ruby was his food and swallowed it. He gained powers by swallowing the magic ruby and was able to resist his enemy, the dragon king. The place where the dragon king vomited the frog king is called Hpa-An (lit. 'vomit frog'). The impressive statues of these figures can be seen in the Shwe Yin Myaw Pagoda's compound.

Hpa-An has a tropical monsoon climate (Köppen climate classification Am). Temperatures are very warm throughout the year, although maximum temperatures are somewhat depressed in the monsoon season due to heavy cloud and rain. There is a winter dry season (November–April) and a summer wet season (May–October). Torrential rain falls from June to September, with over 1,100 millimetres (43 in) falling in July and August alone.

Kayin State Cultural Museum is located in Hpa-An. Mount Zwegabin and Mount Taung Wine are attractive places for visitors, as well as Kyauk Ka Lat Pagoda in which the sacred hair relic of Buddha is enshrined. Hpa An is famous for many limestone caves, like

• Bayin Nyi Naung Cave,
• Yathae Byan Cave,
• Kawgon Cave (or Kawgoon Cave),
• Kaw-ka-thaung Cave and
• Saddan Cave
• Linno Cave

Such caves are well worth visiting because of their incredibly beautiful landscapes and ancient Buddha images and other cultural items in them which were once less known due to regional instability. The Shwe Yin Myaw Pagoda and Thit Hta Man Aung Pagoda are in the center of Hpa-an. Enjoying the beauty of Than Lwin River from the platform of the pagoda is an opportunity that should not be missed. Other interesting places are Kyone Htaw Waterfall which is 2 hours driving from Hpa-an, and the Saddan Cave (mentioned above) which is the biggest and longest cave in Kayin State. The beautiful Kan Thar Yar Lake and its bridge are the heart of Kayin State.
