Abby Newman is a fictional character from the American CBS soap opera The Young and the Restless. The character was introduced on November 13, 2000, as the daughter of Ashley Abbott (Eileen Davidson) and Victor Newman (Eric Braeden). The role was portrayed by Darcy Rose Byrnes as a child until 2008, when the character was rapidly aged to a teenager, with Hayley Erin assuming the role the following year. In 2010, the character was rapidly aged again to an adult, with Marcy Rylan cast as Erin's replacement.

In 2010, Abby was romantically linked with Daniel Romalotti. Soon after, she began flirting with Daniel Romalotti when the two begin sharing romantic interactions. Abby had sex with Daniel in the Newman pool house, and she recorded it for her reality show. Abby and Daniel's relationship was outed when Nikki Newman and Daniel's mother, Phyllis Summers, saw Abby and Daniel making out in public. Their relationship continued for a while, but when Abby found out that Daniel fathered a child with Daisy Carter, she broke up with him.  Upon Abby's return, Abby was romantically linked to Marco Dapper's Carmine Basco, when the two begin dating much to him being shunned by the town, but Abby is able to convince some of them that Carmine is a good soul. However the relationship wasn't given closure upon Rylan's exit from the soap opera. Dapper admitted in an interview that the writers "didn't really know what to do with him after Abby left the first time". He also stated that he hoped Carmine would have more of a "darker turn", and that he still believes there is a "left over spark" with Abby as their storyline "was never finished" and "nothing was wrapped up properly".  Shortly after her failed relationship with Carmine, Abby took romantic interest in Detective Ignacio Serricchio's Alex Chavez, and they began dating. However, the relationship was short-lived when the writers soon began developing Abby's relationship with Redaric Williams's Tyler Michaelson. According to Williams, Tyler is "intrigued" by Abby's unpredictable nature and said that their natural attraction could lead to romance. However, Williams hinted that Tyler's interest in Abby could be his attempt to "suppress his feelings" for Lily. Abby and Tyler's relationship faced some interference from Tyler's ex-fiancee, Mariah Copeland, but she seemed to back off leading to Tyler proposing to Abby and they became engaged. However, Abby breaks off the engagement when Mariah's interferences causes Abby to believe Tyler is still in love with Mariah.
