The Mustermesse Basel (short "muba") was a fair in the city of Basel, Switzerland, named after the Mustermesse (in English: Sample fair) concept. The first fair took place in 1917, and the latest fair took place in 2019.

The first fair was a demonstration of the industrial development of Switzerland and opened on April, 14 1917. It had 831 exhibitors spread out over 6,000 square meters, and exceeded expectations by hosting over 300,000 visitors.

In 1923, it was the site of a fire that completely destroyed the halls of the Mustermesse. Even before the fire, an architectural competition had been held to replace the provisional halls. Two new halls were built two years later.

The number of visitors increased rapidly over the years following the fire. In 1966, it had more than 1,000,000 visitors.
