With Stevie, Scottie, and Charlie on the rise, and Lula, Lucy, Eloise, and Lucia all in style, we're predicting a rise in baby girls called Louie. Fitting the "boyish-nicknames-for-girls" trend, it may additionally be used as a nickname of classic Louisa and Louise. 
 
Actors Jeremy Allen White and Addison Timlin chose Louie as a nickname for their daughter, Dolores Wild, born in 2020, while content creator Chelsea Jennings gave the name to her daughter born in 2026, a sibling to Remi, Madden, and Scotty. 
 
Given to just 17 girls in a recent year (compared to 497 boys), it is a rare option as a given name but perhaps not forever.
