Which Lego theme includes police stations and fire stations?

The LEGO theme that includes police stations and fire stations is LEGO City.

LEGO City is built around familiar urban and everyday settings, including emergency services, transport, construction, space exploration, and ordinary community life. Police and fire sets are especially recognizable parts of the theme: children can build stations, vehicles, rescue equipment, and minifigure teams, then connect them into an imaginary city.

The theme developed from earlier LEGO product lines that portrayed towns, roads, emergency vehicles, and public services. LEGO City was introduced in 2005 as a successor to the LEGO World City line and became one of the company’s central modern themes. Its realistic, contemporary setting distinguishes it from fantasy-oriented themes such as LEGO Ninjago.

LEGO Creator can also include individual buildings and vehicles, and LEGO Friends has its own emergency-service sets, but police and fire stations as parts of a broad city system are characteristic of LEGO City.
