The Sinhalese (Sinhala: siNhl jaatiy Sinhala Jathiya, also known as Hela) are an Indo-Aryan-speaking ethnic group native to the island of Sri Lanka. They constitute about 75% of the Sri Lankan population and number greater than 16.2 million. The Sinhalese identity is based on language, historical heritage and religion. The Sinhalese people speak the Sinhalese language, an Indo-Aryan language, and are predominantly Theravada Buddhists, although a small percentage of Sinhalese follow branches of Christianity.

The form of Buddhism in Sri Lanka is known as Theravada (school of elders). The Pali chronicles (e.g., the Mahavansa) claim that the Sinhalese as an ethnic group are destined to preserve and protect Buddhism. In 1988 almost 93% of the Sinhalese speaking population in Sri Lanka were Buddhist. Observations of current religious beliefs and practices demonstrate that Sinhalese as a religious community have complex worldview as Buddhists. Due to the proximity and on some occasions similarity of certain doctrines, there are many areas where Buddhists and Hindus share religious views and practices. This can lead to the opinion that Buddhists have adopted religious elements from Hindu traditions in their religious practices. Some of these practices may relate to ancient indigenous beliefs and traditions on spirits, worship of deities and godlings and some figures appear to demons. Some of these demonic figures are used in healing rituals and may be native to the island.  Prominent Sri Lankan anthropologists Gananath Obeyesekere and Kitsiri Malalgoda used the term "Protestant Buddhism" to describe a type of Buddhism that appeared among the Sinhalese in Sri Lanka as a response to Protestant Christian missionaries and their evangelical activities during the British colonial period. This kind of Buddhism involved emulating the Protestant strategies of organising religious practices. They saw the need to establish Buddhist schools for educating Buddhist youth and organising Buddhists with new organisations such as the Young Men's Buddhist Association, as well as printing pamphlets to encourage people to participate in debates and religious controversies to defend Buddhism.  There is a significant Sinhalese Christian community, in the maritime provinces of Sri Lanka. Christianity was brought to the Sinhalese by Portuguese, Dutch, and British missionary groups during their respective periods of rule. Most Sinhala Christians are Roman Catholic; a minority are Protestant. Their cultural centre is Negombo.  Religion is considered very important among the Sinhalese. According to a 2008 Gallup poll, 99% of Sri Lankans considered religion an important aspect of their daily lives.
