The Massachusetts House of Representatives is the lower house of the Massachusetts General Court, the state legislature of Massachusetts. It is composed of 160 members elected from 14 counties each divided into single-member electoral districts across the Commonwealth. The House of Representatives convenes at the Massachusetts State House in Boston, the state capital of Massachusetts.

The Massachusetts General Court, formally the General Court of Massachusetts, is the state legislature of the Commonwealth of Massachusetts located in the state capital of Boston. The name "General Court" is a holdover from the earliest days of the Massachusetts Bay Colony, when the colonial assembly, in addition to making laws, sat as a judicial court of appeals. Before the adoption of the state constitution in 1780, it was called the Great and General Court, but the official title was shortened by John Adams, author of the state constitution. It is a bicameral body. The upper house is the Massachusetts Senate which is composed of 40 members. The lower body, the Massachusetts House of Representatives, has 160 members; until 1978, the state house had 240 members. It meets in the Massachusetts State House on Beacon Hill in Boston.
