The Tanzanian Championship League (known as the NBC Championship League for sponsorship reasons) is the second-highest football league in Tanzania. It is made up of sixteen teams that play thirty rounds, home and away. The league was formed in 1930.

The top two teams at the end of the season get promoted to the Tanzanian Premier League, while the third and fourth go into a playoff with two last-placed teams not eligible for automatic relegation. The last two teams are relegated to the first division, while the last four go into a playoff. The two winners in the playoffs are retained, while the two losing teams are relegated to the First League.
