look up any word, like dirty sanchez:
 
1.
An affectionate nickname for the South Shore suburbs of Boston, Massachusetts. The "epicenter" of the Irish Riviera are the towns of Scituate and Marshfield. However, from north to south, Weymouth, Hingham, Hull, Cohasset, Duxbury, and Kingston are also considered to be part of the "Riviera."
The close-to-Boston suburbs of Milton, Quincy, and Braintree are arguably considered a part of the "Irish Riviera." They are definitely a part of the South Shore.

Inland South Shore towns including Holbrook, Abington, Rockland, Norwell, Hanover, and Pembroke are often considered part of the "Irish Riviera."

The Marshfield neighborhood of Fieldston is the most Irish-American section of the second-most Irish-American suburb in the country. The town of Stoneham, north of Boston, home to figure skater Nancy Kerrigan, has the highest-percentage of people with Irish ancestry in the USA.
