Goalball classification is the classification system for goalball. Goalball players with a disability are classified into different categories based on their vision based disability type. The classification is handled by the International Blind Sports Association.

Goalball classification at the Paralympic Games is the basis for determining who can compete in the sport, and within which class. It is used for the purposes of establishing fair competition. Entry is eligible to male and female athletes with a visual disability in one of the three blind sport classifications: B1, B2 and B3. The blind classifications are based on medical classification, no functional classification. This sport has rules that were designed specifically with people with disabilities in mind.

The sport is governed by the International Blind Sports Association. In Australia, the Australian Paralympic Committee is the National Federation for the sport.

As of 2012^[update], people with visual disabilities are eligible to compete in this sport. Both men and women are eligible to play.

The sport was created by the International Blind Sports Association as one intentionally not based on able-bodied sport. It was created to deal with specific needs of blind sport competitors.

The sport was created in 1946 for veterans who were blind. In 1992, the International Paralympic Committee formally took control of governance for disability sport.

Athletes are classified by their degree of visual impairment as follows:

All athletes wear blindfolds while playing to ensure even level of plays amongst competitors with different degrees of visual impairment.^{[citation needed]}
