Daniel Romalotti is a fictional character on the CBS soap opera The Young and the Restless. The role has most notably been portrayed by Michael Graziadei since 2004.

Daniel is the son of Phyllis Summers (Michelle Stafford/Sandra Nelson/Gina Tognoni) and Danny Romalotti (Michael Damian), however a later storyline revealed that Daniel's biological father is a man named Brian Hamilton. Daniel's major storylines have included a love story and marriage with Lily Winters (Christel Khalil/Davetta Sherwood), of which their parents disapproved, as well as being married to Amber Moore (Adrienne Frantz). Daniel fathered a child named Lucy after the mother, Daisy Carter (Yvonne Zima), raped Daniel. Other storylines include his strong friendship with Kevin Fisher (Greg Rikaart), the death of Cassie Newman (Camryn Grimes), and short-lived romances with Abby Newman (Marcy Rylan/Melissa Ordway) and Eden Baldwin (Jessica Heap).

The character was first portrayed by twins Desiree and Hannah Wheel from 1994 to 1996, after which Michael McElroy took over the recurring role from 1996 to 1997. Chase MacKenzie Bebak portrayed Daniel from 1997 to 1998, followed by Roland Gibbons, who had a brief stint until the character was written out.

Subsequently, the character was rapidly aged, with Cam Gigandet assuming the role on March 10, 2004. The actor was fired after only a few days, and he last aired as Daniel on May 6, 2004. The role was recast with Owen Beckman, but the actor was also fired soon after landing the role; as opposed to Gigandet, Beckman's scenes were deleted when Michael Graziadei was cast in the role, who debuted on May 10, 2004. In May 2009, Graziadei signed a new contract with the soap, but in 2012, he chose not to renew his contract. He made his last appearance on January 3, 2013. However, Graziadei later reprised the role for four episodes from July 30 to August 2, 2013, to help usher his onscreen mother, Michelle Stafford, out of the series.

In July 2016, Entertainment Weekly reported that Graziadei would briefly return on August 25, 2016, coinciding with The Young and the Restless's 11,000th episode.

In September 2022, it was announced Graziadei would return; he returned on November 21 of the same year.

Daniel was born off-screen on August 17, 1993; his birth year has since been revised to 1987. Daniel first arrived in Genoa City in 2004 after returning from boarding school to live with his mother, Phyllis Summers. Because she did not raise him as a child, Daniel resented Phyllis as well as her boyfriend, chemist Damon Porter. Daniel then befriended Kevin Fisher, who was desperate to regain some respect after performing some not so nice deeds. Daniel agreed to help him out in exchange for hooking him up with Mackenzie Browning. The two had a lowlife named Alex come on to Lily Winters too strong, so that Kevin could rescue her and that she would like him. Alex went too far and slipped her a date rape drug and attempted to rape her. However, Kevin did arrive in time to "save" her. When Alex kept threatening Daniel and Kevin, Phyllis found out, and she and Damon scared Alex enough to get him out of town. Daniel then decided to give Phyllis a chance.

Daniel had a romance with Lily Winters in 2005, after he was involved in an accident with Cassie Newman, resulting in her death. Suffering memory loss from the accident, Daniel could not remember that fourteen-year-old Cassie was driving in an ill-fated attempt to drive a drunken Daniel home herself. Daniel and Lily then ran away to Los Angeles to escape vehicular homicide charges, and a Romeo and Juliet-style romance unfolded. The fugitives were caught, and Daniel was soon exonerated. Lily's furious parents, Neil and Dru Winters, soon sent her away to boarding school, leaving Daniel devastated. Lily returned in February 2006, and they reunited and eloped in Las Vegas. Later on, Alex returned to blackmail Daniel and Kevin. Daniel then decided to come clean to Lily, who then told her parents. However, she decided to forgive him as did her parents.
