Legoland Discovery Centre is an indoor family attraction chain operated by British leisure group Merlin Entertainments. Featuring models and attractions inspired by the Lego building toys, the Discovery Centres are smaller and indoor versions of the Legoland theme parks located around the world.

A family entertainment center (FEC) in the entertainment industry, also known as an indoor amusement park, family amusement center, family fun center, soft play, or simply fun center, is a small amusement park marketed towards families with small children to teenagers, often entirely indoors. They usually cater to "sub-regional markets of larger metropolitan areas." FECs are generally small compared to full-scale amusement parks, with fewer attractions, a lower per-person per-hour cost to consumers than a traditional amusement park, and not usually major tourist attractions, but sustained by an area customer base. Many are locally owned and operated, although there are a number of chains and franchises in the field. Some, operated by non-profit organizations as children's museums or science museums, tend to be geared toward edutainment experiences rather than simply amusement.
