Katie Sugden (also Addyman and Macey) is a fictional character from the British ITV soap opera Emmerdale, played by Sammy Winward.

On 10 July 2001, Rick Fulton of the Daily Record reported that Winward had joined the cast as Katie alongside Raine Davison, who played Eve Birch.

However, Andy is given counterfeit money by Cain Dingle (Jeff Hordley) and takes Katie for a romantic meal at Chez Marlon restaurant, ruining Robert's plan.

Katie is also put out when Andy's half-brother Daz Eden (Luke Tittensor) moves in with them and the couple struggle to deal with his delinquent behavior.

Katie says goodbye to Donna and Robert begs her to stay but she leaves with Cain's sister Chas (Lucy Pargeter).

Katie later sleeps with David Metcalfe (Matthew Wolfenden) which ends his relationship with Del Dingle (Hayley Tamaddon).

Grayson's mother, Rosemary King (Linda Thorson), is delighted and encourages Katie, hoping for grandchildren as Perdita can't have children.

However, Katie gets pregnant but threatens to have an abortion when Perdita leaves Grayson for Sadie's ex-lover and their brother-in-law Matthew (Matt Healy).

However, the ceremony is ruined when Carl – upon discovering that Matthew is partly the reason why their family's company is now under liquidation – confronts him and exposes his brother's involvement in the death of Anna's father Donald (Michael Jayston), who recently died of a heart attack.

The following day, the Kings are kicked out of Home Farm after being declared bankrupt; Anna later departs the village after attending Matthew's funeral and bidding Katie farewell in respect of their friendship.

New owners, Mark (Maxwell Caulfield) and Natasha Wylde (Amanda Donohoe), arrive and allow Katie to keep her business at Home Farm.

Andy and Katie later become close once more when she discovers that he is suffering from anger issues which ended his relationship with Adele Allfrey (Tanya Vital).

Andy later blames Katie and her affair with Robert for his anger issues and when she defends herself, he smashes a mug against the wall, witnessed by Sarah.

After he investigates the theft of two horses from her stables, Katie begins a relationship with police officer Nick Henshall (Michael McKell), despite Andy's reservations.

He then tells Katie that he had started the fire and committed the burglary and silent phone calls because he had wanted her to need him to rescue her and keep her safe.

When Declan's daughter, Mia (Sapphire Elia), dies in a car crash, he reveals that he was not her biological father and Katie supports him through his grief.

However, she does move in with him at Home Farm and they are happy together until Declan's half-sister, Megan (Gaynor Faye), visits and takes an immediate dislike to Katie.

Megan tells Katie about Declan's money troubles being the reason he had contacted her and asked for financial backing with the festival, causing them to argue.

Katie supports Megan when she reveals that she gave her son, Robbie Lawson (Jamie Shelton) up for adoption when she was younger.

In retaliation, as Declan refuses to ask him to leave, she manipulates a situation in which Robbie tries to kiss her and uses the CCTV to film him attacking her, wanting to expose his true colours.

Katie later considers accepting Steve Harland's (Tom Mannion) offer to invest in a racehorse, but Declan buys it for her instead.

Wanting revenge, Katie throws a party at Home Farm to "celebrate" the festival and invites Charity and her husband Jai Sharma (Chris Bisson).

Katie later tells Chas that she felt in the way as Andy had enough problems involving his ex-girlfriend Debbie Dingle (Charley Webb) and their children.

When Katie discovers Declan had let her horses out of the stables and free into the village, she enlists Adam's help to round them back up and apologizes to him for using him, but her forgives her and reveals that he did not mind as he was attracted to her.

He tries to make amends with her, but she mistakenly believes that was only showing concern as he wanted to know if she would tell anyone about the body and she leaves angrily.

Katie arranges a meeting with businessman Gil Keane (David Easter) who wants to buy all the properties that Declan is selling and refuses to allow the sale of Andy's house.

Adam accepts the bet and buys Katie a drink, later taking her home where he listens to her concerns about Declan lashing out at Megan.

When Chas returns from a holiday in France, Katie helps repair her relationship with Adam's uncle, James Barton (Bill Ward).

In October, Robert (now Ryan Hawley), returns to the village and moves into Home Farm with his new fiancée Chrissie White (Louise Marwood).

When Andy discovers that Robert and Chrissie have pulled out of the farm deal, he furiously confronts Katie and tells her not to attend the wedding and considers moving out and ending their marriage.
