Sarawak exhibits notable diversity in ethnicity, culture, and language. The Sarawakian culture has been influenced by Bruneian Malays of the coastal areas. Substantial cultural influences also came from the Chinese and British cultures.

Interracial marriages, formerly rare or between closely related tribes, are increasingly common.^[1]

Iban's are considered proto-Malays, however their culture has been unaffected by Islamic culture.^[2] While many communities have converted to Christianity, some continue to follow indigenous beliefs.^[3] Customary practices, including jural rules, rituals, and social customs, are collectively known as adat and remain important for Ibans. It differs from the Malay adat in that it is entwined with traditional religious beliefs, and in that some of it can be carried out through law.^[4]

The Iban longhouse functions as a community, each holding several families (over 50 in some cases) related through blood and marriage. A communal corridor (the ruai) runs through the building, and is the location of communal activities, such as work, socialising, celebrating, and discussing community matters. Each Iban longhouse has a head (tuai rumah), determined by community vote upon the death of their predecessor, who acts as a leader and an arbitrator. The tuai rumah reports to the penghulu, who leads several longhouses. In the modern era, the tuai rumah is also responsible for implementing government policies in these communities.^[5] Headhunting was once an important tradition for the Ibans, with Sarawak once nicknamed the "Land of the Headhunters". It was part of a heroic warrior code where tribal prestige was determined by its capacity for warfare. The custom is no longer observed, after being made illegal shortly after the Second World War.^[6]

The closely related Lun Bawang and Kelabit tribes have undergone significant cultural change due to conversion to Christianity, affecting their religious and ethnic identities. Each village now has a church, which has taken over the social and community functions previously associated with the longhouse.^[7] The Penan people were one of the last remaining indigenous groups. While a minority retain traditional nomadic ways, most have settled down and adopted modern clothing, with less attention paid to traditional hairstyles, dangling earlobe modification, and traditional rattan bangles.^[8][9]

Sarawak Cultural Village is located at the foot of Mount Santubong, Kuching. Known as the "living museum", it showcases the various ethnic groups carrying out traditional activities in their respective traditional houses. Cultural performances are presented here.^[10][11] The Sarawak State Museum houses a collection of artefacts such as pottery, textiles, and woodcarving tools from various ethnic tribes in Sarawak, as well as ethnographic materials of local cultures.

The Batang Ai Resort and Bawang Assan Iban longhouses allow the visiting guests to have an overnight stay and to participate in traditional Iban daily activities.^[24][25] Other longhouses include: Iban longhouses in Kapit,^[26] Bidayuh longhouses in Kuching,^[27] Kelabit longhouses in Bario,^[28] Lun Bawang longhouses in Ba'kelalan,^[29] and Melanau wooden houses in Sibu.^[30] Main Bazaar and Carpenter Street are the two notable streets in Chinatown, Kuching.^[31] India Street in Kuching is notable for its textile products. An Indian–Muslim mosque can be found in the vicinity.^[32][33]

The oral tradition has been part of the culture of the various indigenous groups in Sarawak for generations. It is used for passing on life lessons, traditions, and values to the younger generation. The stories are told repeatedly by the elders to the younger ones, such as in storytelling sessions on special occasions and through traditional performances.^{[46][note 1]} Some of these traditional practices are the Iban's Ngajat dances,^[47] Renong (Iban vocal repertory),^[48] Ensera (Iban oral narratives),^{[49][note 2]} and epic storytelling by the Kayan and Kenyah.^[50][51] The Borneo Literature Bureau existed from 1958 until 1977; it encouraged the documentation of local cultures, local authors, and publications in English, Chinese, Malay, Iban and other native languages.
