The Culture of Malaysia draws on the varied cultures of the different people of Malaysia. The first people to live in the area were indigenous tribes that still remain; they were followed by the Malays, who moved there from mainland Asia in ancient times. Chinese and Indian cultural influences made their mark when trade began with those countries, and increased with immigration to Malaysia. Other cultures that heavily influenced that of Malaysia include Persian, Arabic and British. The many different ethnicities that currently exist in Malaysia have their own unique and distinctive cultural identities, with some crossover.

Arts and music have a long tradition in Malaysia, with Malay art dating back to the Malay sultanates. Traditional art was centred on fields such as carving, silversmithing, and weaving. Islamic taboos restricted artwork depicting humans until the mid-20th century. Performing arts and shadow puppet shows are popular, and often show Indian influences. Various influences can be seen in architecture, from individual cultures in Malaysia and from other countries. Large modern structures have been built, including the tallest twin buildings in the world, the Petronas Twin Towers. Malaysian music has a variety of origins, and is largely based around percussion instruments. Much early Malaysian literature was based on Indian epics, which remained unchanged even as Malays converted to Islam; this has expanded in recent decades. English literature remained restricted to the higher class until the arrival of the printing press. Locally created Chinese and Indian literature appeared in the 19th century.

Cuisine is often divided along ethnic lines, but some dishes exist which have mixed foods from different ethnicities. Each major religious group has its major holy days declared as official holidays. Official holidays differ by state; the most widespread one is Merdeka day which celebrates the independence of Malaya. Although festivals often stem from a specific ethnic background, they are celebrated by all people in Malaysia. Traditional sports are popular in Malaysia, while it has become a powerhouse in international sports such as badminton. Malaysia hosted the Commonwealth Games in 1998, the first Commonwealth Games where the torch passed through more countries than England and the host.

The Malaysian government has taken the step of defining Malaysian Culture through the "1971 National Culture Policy", which defined what was considered official culture, basing it around Malay culture and integrating Islamic influences. This especially affected language; only Malay texts are considered official cultural texts. Government control over the media is strong, and most media outlets are related to the government in some way.

Malaysia consists of two distinct geographical regions: Peninsular Malaysia and East Malaysia. Malaysia was formed when the Federation of Malaya merged with North Borneo (today the province of Sabah), Sarawak, and Singapore (seceded 1965) in 1963, and cultural differences between Peninsular and East Malaysia remain. During the formation of Malaysia, executive power was vested in the Perikatan (later the Barisan Nasional) coalition of three racially based political parties, namely the United Malays National Organisation (UMNO), Malaysian Chinese Association (MCA), and Malaysian Indian Congress (MIC). UMNO has dominated the coalition from its inception. Although Islam is the official state religion, the Constitution of Malaysia guarantees freedom of religion.

Malaysia is a multi–ethnic, multicultural, and multilingual society, and the many ethnic groups in Malaysia maintain separate cultural identities. The society of Malaysia has been described as "Asia in miniature". The original culture of the area stemmed from its indigenous tribes, along with the Malays who moved there in ancient times. Substantial influence exists from the Chinese and Indian cultures, dating back to when trade with those countries began in the area. Other cultures that heavily influenced that of Malaysia include Persian, Arabic, and British. The structure of the government, along with the racial balance of power caused by the idea of a social contract, has resulted in little incentive for the cultural assimilation of ethnic minorities in Malaya and Malaysia. The government has historically made little distinction between "Malay culture" and "Malaysian culture".

The Malays, who account for over half the Malaysian population, play a dominant role politically and are included in a grouping identified as bumiputra. Their native language, Bahasa Malaysia, is the national language of the country. By definition of the Malaysian constitution, all Malays are Muslims. The Orang Asal, the earliest inhabitants of Malaya, formed only 0.5 percent of the total population in Malaysia in 2000, but represented a majority in East Malaysia, Borneo. In Sarawak and Sabah, most of the non-Muslim indigenous groups are classified as Dayaks, and they constitute about 40 percent of the population in the state. Many tribes have converted to Christianity. The 140,000 Orang Asli, or aboriginal peoples, comprise a number of different ethnic communities living in peninsular Malaysia.

The Chinese have been settling in Malaysia for many centuries, and form the second-largest ethnic group. The first Chinese to settle in the Straits Settlements, primarily in and around Malacca, gradually adopted elements of Malaysian culture and intermarried with the Malaysian community and with this, a new ethnic group called emerged, the Peranakan ("Straits Chinese"). These Chinese have adopted Malay traditions while maintaining elements of Chinese culture such as their largely Buddhist and Taoist religion. The more common Chinese varieties spoken in Peninsular Malaysia are Cantonese, Mandarin, Hokkien, Hakka, Hainanese, and Fuzhou.
