The religious practices, social customs and cultural standards of the Americo-Liberians had their roots in the antebellum American South. The settlers wore top hat and tails and modeled their homes on those of Southern slaveowners.[90] Most Americo-Liberian men were members of the Masonic Order of Liberia, which became heavily involved in the nation's politics.

Liberia has a long, rich history in textile arts and quilting, as the settlers brought with them their sewing and quilting skills. Liberia hosted National Fairs in 1857 and 1858 in which prizes were awarded for various needle arts. One of the most well-known Liberian quilters was Martha Ann Ricks,[92] who presented a quilt featuring the famed Liberian coffee tree to Queen Victoria in 1892. When President Ellen Johnson Sirleaf moved into the Executive Mansion, she reportedly had a Liberian-made quilt installed in her presidential office.

A rich literary tradition has existed in Liberia for over a century. Edward Wilmot Blyden, Bai T. Moore, Roland T. Dempster and Wilton G. S. Sankawulo are among Liberia's more prominent authors. Moore's novella Murder in the Cassava Patch is considered Liberia's most celebrated novel.

Liberian cuisine heavily incorporates rice, the country's staple food. Other ingredients include cassava, fish, bananas, citrus fruit, plantains, coconut, okra and sweet potatoes. Heavy stews spiced with habanero and scotch bonnet chillies are popular and eaten with fufu. Liberia also has a tradition of baking imported from the United States that is unique in West Africa.

According to the 2008 National Census, 85.5% of the population practices Christianity. Muslims comprise 12.2% of the population, largely coming from the Mandingo and Vai ethnic groups. Traditional indigenous religions are practiced by .5% of the population, while 1.5% subscribe to no religion. A small number of people are Bahá'í, Hindu, Sikh, or Buddhist. Concurrent participation in indigenous religious secret societies such as Poro and Sande is common, with some Sande societies practicing female genital mutilation.

The Constitution provides for freedom of religion, and the government generally respects this right. While separation of church and state is also mandated by the Constitution, Liberia is considered a de facto Christian state. Public schools offer biblical studies, though parents may opt out their children. Commerce is prohibited by law on Sundays and major Christian holidays. The government does not require businesses or schools to excuse Muslims for Friday prayers.
