The second season of Dynasty, an American television series based on the 1980s prime time soap opera of the same name, originally aired in the United States on The CW from October 12, 2018, through May 24, 2019.

Series regulars added for the second season include Ana Brenda Contreras as Cristal Jennings, Maddison Brown as Kirby, and Sam Underwood as Adam Carrington, Blake and Alexis's eldest son.

Notable recurring characters featured in season two include Monica Colby (Wakeema Hollis); Dominique Deveraux (Michael Michele); Claudia Blaisdel (Brianna Brown); Liam Ridley (Adam Huber); Ada Stone (Katherine LaNasa); Melissa Daniels (Kelly Rutherford); and Hank Sullivan (Brent Antonello).

[27][28] A May 2018 press release teased that the show would introduce Blake's half-sister Dominique Deveraux, Jeff and Monica's mother, in season two.

[3][39][40] Maddison Brown was also cast as Anders's daughter, Kirby,[41] and Sharon Lawrence portrayed the guest role of Liam's mother, Laura Van Kirk.

[4] Grant Show's wife Katherine LaNasa joined the cast in October 2018 in the recurring role of Ada Stone.

Praise was given to the stunning and campy scenes that "make the show worth watching," such as The Great Gatsby inspired party and the Wizard of Oz dream sequence.

Makitalo was also disappointed in Alexis's development in the second season, stating: Elizabeth Gillies is the clear star of the reboot, although it appears that the producers believe it is Nicollette Sheridan.
