What is the meaning of the name Marilou ?

The baby name Marilou is a Female name , 3 syllables long and is pronounced US: /ˈmærɪluː/ (MAIR-ih-loo); FR: /maʁiˈlu/ (mah-ree-LOO).

Marilou is French, Spanish in Origin.

Marilou is a compound feminine name formed in two main traditions: in English it blends Mary and Lou, while in French it contracts Marie and Louise into a smooth modern form. The components carry layered meanings - Mary/Marie from Hebrew Miryam (often interpreted as “beloved,” “sea,” or by folk etymology “star of the sea”) and Lou/Louise from Germanic Hludwig, “famous warrior.” Together, Marilou suggests a poetic mix of devotion and renown.

The name came into wider use in the 20th century, especially in North America and Francophone countries, echoing the popularity of double names. In the Philippines, Marilou also functions as a familiar blend of Maria and Lourdes. Variant spellings and forms include Marylou, Mary Lou, Marilu/Marilú (Spanish), Marilou (French), Marie-Lou, and the formal doublets Mary Louise and Marie-Louise. Nicknames and short forms such as Mari, Lou, Lulu, and Malou are common.
