DeAnna Marie Stagliano (née Pappas; born November 20, 1981) is an American television personality best known for her participation in season 11 of the ABC reality television show The Bachelor, and season 4 of The Bachelorette.

Pappas, of Greek heritage, who is the middle of three children, was born in Marietta, Georgia, and shortly thereafter moved to Kentucky with her mother and siblings. When she was twelve years old, her mother died of cancer and she relocated with her brother, Thomas, and sister, Chrissy, to Newnan, Georgia, to live with her father. She is a one-time resident of Nashville, Tennessee.

After high school she attended Georgia Military College and received a degree in General Studies.

In 2007, Pappas decided to audition for The Bachelor, a reality television dating game show on ABC Television. She made it to the final rose ceremony, where bachelor Brad Womack rejected both women. He was chastised by Ellen DeGeneres, who later retracted her statement. ABC Television then tapped Pappas to star in The Bachelorette. The news was broken to her by Ellen DeGeneres while she was a guest on DeGeneres' daytime talk show.

In the 2008 season of The Bachelorette, Pappas eventually rejected single dad Jason Mesnick and accepted the marriage proposal of professional snowboarder Jesse Csincsak. Their relationship lasted a few months before the engagement was called off. Mesnick went on to become The Bachelor in 2009.

In October 2008, Pappas won Fox Reality Channel's "Golden Realtini", given to the most memorable reality performer of the year.

During her engagement, in 2009, Pappas became the co-host of Get Married on Lifetime reporting on wedding planning.

In late 2011, DeAnna was on the "Big Fat Greek Bachelorette Party" episode of the Oxygen cable-channel show Bachelorette Party.
