The episode reached 503,000 people in total between RTÉ One and RTÉ One +1.
The hour-long show was also a talking-point on social media as it aired, trending at number one on Twitter.
Brigie de Courcy, Executive Producer, Fair City, said: "Fair City is a huge team effort and so very many people have been involved over all of the years and the 30th anniversary really is a collective celebration of all that work.
"It's a production that supports and nourishes talent in Ireland, both behind of and in front of the cameras, and has moved with the times to showcase how people across the country can resonate with the trials and tribulations of a community in a Dublin suburb.
"I would like to thank everyone involved in Fair City down through the years, and our audience for all of their continued support."
During the episode, kidnapper Ciarán Holloway (Johnny Ward) returned to Carrigstown, only to find himself face to face with Barry (Pat Nolan), who had just been attacked by a mystery assailant.
Viewers will find out in the coming days and weeks what Ciarán's motive for returning to Carrigstown is.
