The 1. deild karla is the second tier of men's football in Iceland. It features clubs that compete for promotion to the top division, known as the Úrvalsdeild karla. The league typically consists of several teams that play each other in a round-robin format, with points awarded for wins and draws. Each season, the top teams in the 1. deild karla have the opportunity to move up to the Úrvalsdeild karla, while the lower-performing teams may face relegation to the third tier, called the 2. deild karla. This structure creates a competitive environment for clubs striving for advancement.
