The name is an anglicized form of the Gaelic, Máirín, which was originally used as a diminutive form of Mary.
The name first appeared in the U.S. top 1000 in 1907, coming in as the 898th most popular female name. By 1948, she was the 88th most popular female name in the United States, perhaps due to the fame of Irish actress, Maureen O’Hara (b.1920). As of 2010, Maureen was not in the U.S. top 1000.
As of 2009, Maureen was the 497th most popular female name in France and the 478th most popular in the Netherlands, (2010).
