A trailer park is a neighborhood consisting of an area of land where travel trailers rest. The term may also be used to refer to mobile home parks or manufactured home communities.

In the United States, tornadoes and hurricanes often inflict their worst damage on trailer parks, usually because the structures are not secured to the ground and their construction is significantly less able to withstand high wind forces than regular houses. However, most modern manufactured homes are built to withstand high winds as well as a mainstream home, using hurricane straps and proper foundations.

In the United States, trailer parks are stereotypically viewed as lower income housing whose occupants live at or below the poverty line, have low social status and lead a desultory and deleterious lifestyle. Despite the advances in manufactured home technology, the trailer park stereotype still survives, evidenced in a statement by Presidential adviser James Carville in the course of one of the Bill Clinton White House political scandals, "Drag $1 bills through trailer parks, there's no telling what you'll find"," regarding Paula Jones. It is also seen in the Canadian Mockumentary, Trailer Park Boys.
