A new state for an old nation, Bangladesh has a culture that encompasses elements both old and new. The Bangla language boasts a rich literary heritage, which Bangladesh shares with West Bengal. The first literary text in Bangla is the eighth century Charyapada. Bangla literature in the medieval age was often either religious (e.g. Chandidas), or adaptations from other languages (e.g. Alaol). Bangla literature matured in the nineteenth century. Its greatest icons are the poets Rabindranath Tagore and Kazi Nazrul Islam. Bangladesh also has a long tradition in folk literature, evidenced by Maimansingha Gitika, Thakurmar Jhuli or stories related to Gopal Bhar.

Bangladesh produces about 80 films a year.Mainstream Hindi films are also quite popular, as are films from Kolkata, which has its own thriving Bengali-language movie industry. Around 200 dailies are published in Bangladesh, along with more than 1800 periodicals. However, regular readership is low, nearly about 15% of the population. Bangladeshis listen to a variety of local and national radio programmes from Bangladesh Betar, as well as Bangla services from the BBC and Voice of America. There is a state-controlled television channel, but in the last few years, privately owned channels have grown considerably.

The culinary tradition of Bangladesh has close relations to Indian and Middle Eastern cuisine as well as having many unique traits. Rice and fish are traditional favourites; leading to a common saying that "fish and rice make a Bengali" (machhe bhate bangali). Meat Consumption has increased with higher production in recent years. Bangladeshis make distinctive sweetmeats from milk products; some common ones are Rôshogolla, Chômchôm and Kalojam. The sari (shari) is by far the most widely worn dress by Bangladeshi women. However, the salwar kameez (shaloar kamiz) is also quite popular, and in urban areas some women wear Western attire. Among men, European dressing has greater acceptance. Men also use the kurta-paejama combination, often on religious occasions. The lungi, a kind of long skirt, is widely worn by Bangladesh men.

The most important secular festival is Nôbobôrsho or Bengali New Year, the beginning of the Bengali calendar. Other festivities include Nobanno, Poush parbon (festival of Poush) and observance of national days like Shohid Dibosh.

Cricket is one of the most popular sports in Bangladesh. In 2000, the Bangladesh cricket team was granted test cricket status and joined the elite league of national teams permitted by the International Cricket Council to play test matches. Other popular sports include football (soccer), field hockey, tennis, badminton, handball, kabadi, volleyball, chess, and carom. Kabadi, a 7-a-side team-sport played without a ball or any other equipment, is the national sport of Bangladesh. The Bangladesh Sports Control Board regulates 29 different sporting federations.
