The Code of Massachusetts Regulations (CMR) is the canonical collection of regulations promulgated by various agencies of the Commonwealth of Massachusetts. It is the state counterpart to the national Code of Federal Regulations (CFR).

Regulations which have been approved by an authorized agency according to a procedure established by the legislature have the force of law. This allows the state legislature to delegate the details of certain types of lawmaking to executive agencies.

Updates to the CMR are published in the bi-weekly Massachusetts Register from the Massachusetts Secretary of the Commonwealth. The Code is organized by executive cabinet agency. In citations, the number before the "CMR" refers to the issuing agency, and the numbers thereafter refer to a specific chapter or section.

N.B. the official CMR is available, online, on a subscription basis. An unofficial version of the CMR is available online for free from the Massachusetts Trial Court Law Libraries.

Massachusetts (ⁱ/ˌmæsəˈtʃuːsɨts/), officially the Commonwealth of Massachusetts, is a U.S. state in the New England region of the northeastern United States of America. It is bordered by Rhode Island and Connecticut to the south, New York to the west, and Vermont and New Hampshire to the north; at its east lies the Atlantic Ocean. Massachusetts is the 7th least extensive, but the 14th most populous and the 3rd most densely populated of the 50 United States. The state features two separate metropolitan areas – the eastern Boston metropolitan area and the western Springfield metropolitan area. Approximately two thirds of the state's population lives in Greater Boston, most of which is either urban or suburban. Western Massachusetts features one urban area – the Knowledge Corridor along the Connecticut River – and a mix of college towns and rural areas. Massachusetts is the most populous of the six New England states and has the US's sixth highest GDP per capita.

Jim 'Tough' Barry (c.1891-1967) was an Irish hurling trainer. In a managerial career that lasted for forty years from 1926 until 1966 he guided the Cork senior inter-county team to twelve All-Ireland titles. An amateur boxer and swimmer in his youth Barry is credited with bringing a forward-thinking and holistic approach to preparing players. A tailor by profession, he visited workplaces to talk to employers on behalf of his players, demanded proper meals for his squads after matches, and was renowned for his ability to have them perfectly pitched for the biggest games.
