Bangli Regency (Indonesian: Kabupaten Bangli; Balinese: ᬓᬪᬹᬧᬢᬾ​ᬦ᭄ ᬩᬗ᭄ᬮᬶ, Kabupatén Bangli) is the one and only landlocked regency (kabupaten) of the province of Bali, Indonesia. It covers a land area of 520.80 km², and had a population of 259,392 in 2024. It is bordered by Badung Regency to its west, Gianyar Regency to its west and south, Buleleng Regency to its west and north, Karangasem Regency to its east and Klungkung Regency to its south. The administrative centre is at the town of Bangli.

Up until 1907, Bangli was one of the nine kingdoms of Bali. The capital has a famous Hindu temple, the Kehen Temple, which dates from the 11th century. Bangli also has one village which surrounds a hill, Demulih.

Pura Dalem Galiran is 1.4 km north-west of Bangli. Pura Dalem Penunggekan, 1.3 km south of the town center,

According to the Kehen Temple Inscription stored in the Kehen Temple, it is said that in the 11th century in Bangli Village, an epidemic called kegeringan developed which caused many residents to die. The other residents who were still alive and healthy were scared to death, so they left the village in droves to avoid the epidemic. As a result, Bangli Village became empty because no one dared to live there.

King Ida Bhatara Guru Sri Adikunti Ketana who was reigning at that time tried to overcome the epidemic. After the situation recovered, the king who reigned in the year Caka 1126, on the 10th of the Bright Half Year, Maula Market Day, Kliwon, Chandra (Monday), Wuku Klurut precisely on 10 May 1204, ordered his sons and daughters named Dhana Dewi Ketu to invite the residents to return to Bangli Village to jointly build and repair their respective houses as well as hold ceremonies/yadnya in the months of Kasa, Karo, Katiga, Kapat, Kalima, Kalima, Kanem, Kapitu, Kaulu, Kasanga, Kadasa, Yjahstha and Sadha. In addition, the king also ordered all residents to increase their descendants in the Pura Loka Serana area in Bangli Village and allowed the clearing of forests to make rice fields and water channels. For that reason, at every major ceremony, the residents in Bangli Village must perform prayers. At that time, on 10 May 1204, King Idha Bhatara Guru Sri Adikunti Katana uttered a decree, namely:

Whoever does not submit and violates orders, may that person be struck by lightning without rain or suddenly fall from a bridge without cause, blind eyes without a clamp, after death his soul is tortured by Yamabala, thrown from the sky down into the fires of hell.

Starting from the King's decrees issued on 10 May 1204, that date was determined as the birthday of Bangli City.

In Manikliyu (west side of Bangli Regency), a burial site was excavated in 1997 and 1998 which revealed two large sarcophagi and a bronze kettle drum, representing a unique burial system thus far unknown in Indonesia. The largest sarcophagus (length 206 cm, width 70 cm) is well preserved; the other sarcophagus (length 172 cm, width 69 cm) is partly broken. The bronze kettle drum (height 120 cm, diameter of the tympanon 77 cm) is decorated with eight stars on the tympanon, and human masks on the body. It contained human bones in flexed position that belonged to a young man of Mongoloid type, between 20 and 35 years old; the broken part of his upper face shows that he was killed by the impact of a sharp tool. The burial site also contained carnelians, beads, bronze spirals and bronze finger protectors. Some remnants broken pottery and pottery shards were also found beside the burial site and near the containers.
