Yes; it depends on the religious group. Many Native American peoples continue to follow their ancestral religions. African religions are still practiced--and in India the "indigenous" religion is the main form of religion. Many Japanese still practice Shintoism and many Koreans still practice shamanism.
Modern civilization has had little impact on the spiritual lives of indigenous peoples. They continue to practice indigenous religions. There are thousand of people groups who have not been evangelized.
Of the major religions still practiced today, Hinduism is probably oldest.

Many religions practice or practiced polytheism, including the ancient Greek religion (which is still practiced today), the ancient Roman religion (mostly based on the Greek religion), and many indigenous religions.
Most of the ancient polytheistic religions of the Mesopotamian area are no longer practiced. It may be worth noting, however, that the founder of Judaism, Abraham, began his life in UR, in the southern part of Mesopotamia, before he is said to have moved at God's command to Palestine.Therefore it could be said that Judaism is a Mesopotamian religion that is still practiced today. Since Christianity and Islam both derive from Judaism, it could be said that all three of them are Mesopotamian religions.

Religions are grievous concept of our times, as most of us do not follow what the religions stood for originally. None of the religions preached any impairment to humanity. They always advocated peaceful coexistence. Presently, the indigenous religions are threatened by egotism of religious perceptors and the absence of proper discernment of the holy preachings of the religions at the time of their origin.
