Kampong Junjongan (Malay: Kampung Junjongan) also Kampong Junjungan or simply Junjongan, is a village in the south-east of Brunei–Muara District, Brunei, about 16 kilometres (9.9 mi) from the capital of Brunei, Bandar Seri Begawan. According to 2016 records, the population was 2,006. It is one of the villages within Mukim Pengkalan Batu. The postcode is BH2123.

The village was originally called Kampong Lampaki. Lampaki is a type of bamboo. Later, the name of this village was changed to Kampong Junjongan because in the past it was often visited and became the focus of traders. According to folktales, these people move from town to village to earn a living. At that time, the barter system was still practiced; salted fish is exchanged for fruits. In addition, the name of this village is taken in conjunction with the good quarter from the words disanpat, dijungung which means to be looked up to and respected.

Around the 1930s, this village was only inhabited by approximately 30 people with only 13 houses built. At that time, the spirit of cooperation was very strong among the villagers.

The villagers worked on a coconut plantation scheme that started in 1975. At this time, a total of 63 people were given one lot each which is two acres of land each to be developed for the plant scheme. Whereas in 2000, Koperasi BAKA was established until now working on a local fruit farm planted on 73 hectares of land by 128 members of the village. With the fertile soil, this village also farms local fruits such as durian, rambutan, pulasan, kembayau, binjai and belunu. The Tar Handicraft Entrepreneur (Hadrah) can be classified as percussion music which only uses drums and gongs to accompany the singing during cultural events such as weddings, welcoming guests and so on.
