Wolf

Notable Wolfs like Blitzer, Mankowitz, and Kahn give this name a masculine bent, but nature names are inherently unisex, so we see no reason why Wolf can't be used on a baby girl.

Historically Wolf has been more common among German (where it's pronounced Vulf) and Jewish families, occasionally as a nickname for Wolfgang.

The nickname Wolfie softens and feminizes Wolf, while Wolfe turns it into a surname.

Pronounced WOOLF.
