The New Girl actress gave birth in July 2015, but her and her husband Jacob Pechenik kept schtum on what they decided to call their baby girl. Until now.
The couple revealed their daughter's name is Elsie Otter during a red carpet appearance in New York City.
"It's Elsie…" Deschanel told PEOPLE when she was asked, while her husband added: "Otter".
"Like the animal," Deschanel added.
The 35-year-old gave birth to Elsie in late July, when her rep confirmed she also secretly married Pechenik.
Her rep said at the time: "I am thrilled to confirm that Zooey Deschanel and her husband Jacob Pechenik are new parents to a beautiful healthy baby girl."
The couple announced their engagement in January 2015 after it was revealed Deschanel was pregnant with their child.
At the time, Deschanel told PEOPLE: "Jacob and I are over the moon. We are so excited to meet our little one."
The actress hasn't shared any photos of her daughter or revealed much about her first three months as a mum, but she has compared Elsie to Donald Trump.
Deschanel tweeted in September 2015: "My infant daughter is going to run for president. She remains silent [on] all of the key issues but she’s much cuter than Donald Trump."

Deschanel's New Girl co-star Lamorne Morris has also confirmed Elsie's cuteness.
Speaking to PEOPLE in August, Morris said: "She’s an extremely cute baby. She looks like Zooey.”
