A tithe ( /ˈtaɪð/; from Old English: teogoþa "tenth") is a one-tenth part of something, paid as a contribution to a religious organization or compulsory tax to government. Today, tithes (or tithing) are normally voluntary and paid in cash, cheques, or stocks, whereas historically tithes were required and paid in kind, such as agricultural products (that grown of the land, or fruit of the tree). Several European countries operate a formal process linked to the tax system allowing some churches to assess tithes.

"Tithing" also has unrelated economic and juridical senses, dating back to the Early Middle Ages. See "Tithing (country subdivision)".

Traditional Jewish law and practice has included various forms of tithing since ancient times. Traditional Jews commonly practice ma'aser kesafim (tithing 10% of their income to charity) and take challah. In modern Israel, Jews continue to follow the laws of agricultural tithing, e.g., terumah, ma'aser rishon, terumat ma'aser, and ma'aser sheni. In Christianity, some interpretations of Biblical teachings conclude that although tithing was practiced extensively in the Old Testament, it was never practiced or taught within the first-century Church. Instead the New Testament scriptures are seen as teaching the concept of "freewill offerings" as a means of supporting the church: 1 Corinthians 16:2, 2 Corinthians 9:7. Also, some of the earliest groups sold everything they had and held the proceeds in common to be used for the furtherance of the Gospel: Acts 2:44-47, Acts 4:34-35. Further, Acts 5:1-20 contains the account of a man and wife (Ananias and Sapphira) who were living in one of these groups. They sold a piece of property and donated only part of the selling price to the church but claimed to have given the whole amount and immediately fell down and died when confronted by the apostle Peter over their dishonesty.

Creflo Augustus Dollar, Jr. is an American Bible teacher, pastor, and the founder of the non-denominational World Changers Church International based in Fulton County, Georgia. Creflo Dollar Ministerial Association (formerly called International Covenant Ministries), Creflo Dollar Ministries, and Arrow Records. Each of these enterprises is overseen by Dollar and his wife, Taffi Dollar.

In 1984, Dollar received a Bachelor of Science degree in education from West Georgia College in Carrollton, Georgia. He was awarded an honorary Doctor of Divinity from Oral Roberts University in 1998.

Dollar indicates that he received the vision for World Changers Ministries Christian Center in 1986. He held the church's first worship service in the cafeteria of Kathleen Mitchell Elementary School in College Park, Georgia, with only eight people in attendance and successfully receiving over $100 in contributions from those present. Over the years the ministry has grown rapidly and was renamed World Changers Church International (WCCI). As of 2007, the congregation has grown to 30,000 members with $69 million in revenue (gross cash collections) for 2006. The congregation moved from its original cafeteria location to a modest-sized chapel, adding a weekly radio broadcast and four services each Sunday. On December 24, 1995, WCCI moved into its present location, the 8,500-seat sanctuary known as the World Dome. At a cost of nearly $18 million, it is claimed that the World Dome was built without any bank financing.
