The following is a list of characters that first appeared in the ITV soap opera Coronation Street in 2005, by order of first appearance.

Scooter Makuna

Hiren "Scooter" Makuna first appeared in early 2005 as the boyfriend of Sarah Platt (Tina O'Brien). He was of Indian descent. His character was mostly remembered for not being very bright, having a fondness for fish and getting great pleasure in retrieving junk from skips. Sarah broke up with him in the autumn of 2005 after she had a fling with Jason Grimshaw (Ryan Thomas) and an argument. He left the Street soon afterwards.

Lena Thistlewood

Lena Thistlewood is a friend of Blanche Hunt (Maggie Jones), who first appears in 2005 and regularly visits the Barlow household and she takes a fancy to Ken Barlow (William Roache). She subsequently attends Ken's second wedding to Blanche's daughter, Deirdre Rachid (Anne Kirkbride) in 2005.

After the wedding, Lena booked her car in for an MOT at Webster's Autocentre and hoped to get a certificate without a test; however, mechanic Tyrone Dobbs (Alan Halsall) said it would need one owing to its age. When Lena next visited the garage, she caught Tyrone having sex with Maria Sutherland (Samia Longchambon). As a result, she pretended to be overcome with shock and manipulated Tyrone into giving her a free MOT and Maria into giving her a free haircut. Lena dies off-screen on New Year's Day 2006 and she leaves her dog, Lady Freckles, to Blanche, who renames her Eccles.

Diggory Compton

Diggory Compton was played by Eric Potts. When he arrives in Weatherfield with his daughter Molly (Vicky Binns), Diggory opens the local bakery shop at the end of the street. He tries wooing Liz McDonald (Beverley Callard) by inviting her to a Christmas dinner party; however, she ended up meeting her future husband, drummer Vernon Tomlin (Ian Reddington), at the event. During his time in Weatherfield, Diggory befriends Mike Baldwin (Johnny Briggs). Diggory leaves Weatherfield in July 2006 after his business fails.

Molly visits him in 2008 after falling out with her fiancé Tyrone Dobbs (Alan Halsall). On 5 January 2009, Molly receives a call from the hospital that Diggory's appendix has burst. Several days later, it is revealed Diggory will recover but he will ultimately miss Molly and Tyrone's wedding due to being hospitalised for a week. In December 2010, Diggory is informed by telephone that Molly has died in the tram crash caused by an explosion at the Joinery Bar. Diggory's sister Pam Hobsworth (Kate Anthony) tells Molly's former lover Kevin Webster (Michael Le Vell) the heartbreak of having to inform Diggory of his daughter's death saying she is wondering what words to use to break the news to him. Diggory is not seen at Molly's funeral as he is reportedly too ill to attend.

Jessie Jackson

Jessie Jackson is played by actress Nailah Cumberbatch. She arrives at Underworld with her "twin sister" Joanne (Zaraah Abrahams) to replace departing machinist Sonia Marshall (Tina Gambe) and is the more outgoing one of the two.

Her "twin sister" is later revealed to be her cousin.

Joanne Jackson

Joanne Jackson was played by the actress Zaraah Abrahams. The character and casting was announced in February 2005 and she debuted later that month. Joanne arrived at Underworld with her "twin sister" Jessie and proceeded to cause much amusement by claiming to be identical despite the obvious difference in appearance. Joanne was the shyer of the two and lacks confidence where men are concerned. Abrahams later left the role in 2007 and the character last appeared on 20 July 2007.

Keith Appleyard

Keith Appleyard is played by Ian Redford. Keith is Angela Harris's (Kathryn Hunt) father. When she and her family live in Sheffield, she witnesses a murder. Keith persuades Angela to tell the truth and testify at the trial, which results in their move to Weatherfield under the witness protection scheme. They are also given a new name - Nelson - but don't use it for long. Keith first appears in 2005 to help Angela after her husband Tommy (Thomas Craig) dies. He stays to look after his grandchildren Katy (Lucy-Jo Hudson) and Craig (Richard Fleeshman) after Angela is arrested for Tommy's murder. Katy (the real killer) commits suicide, unable to handle the guilt, and Angela is imprisoned for helping Katy cover up the crime. Keith stays with Craig in Coronation Street, rather than insist Craig join him in Sheffield, feeling Craig has suffered enough - plus, Weatherfield is closer than Sheffield to where Angela is in prison.

After moving in, Keith dates hairdresser Audrey Roberts (Sue Nicholls), who is his opposite in many ways. Keith is always watching the pennies and takes on a paper round to earn some extra money. His hobbies include taxidermy. Keith is widowed, his wife having died between 2003 and 2005. Angela telephones her mother on Christmas Day 2002, and visits her in September 2003, but she has died by the time Keith arrives in 2005. After he and Audrey end things as they are so different, Keith became enemies with builder Charlie Stubbs (Bill Ward). Charlie bills Keith for repairing the leak on the roof but Keith refuses to pay the bill, feeling Charlie has overcharged. In revenge, Charlie removes the roof tiles, insisting he will replace them when Keith pays his bill. Keith rings the police but the police say they can't help as it isn't a police matter. Keith is delighted to see Charlie replacing the tiles, thinking that he has won, until Charlie reveals that he is his new landlord.

Keith is horrified and says that the landlord would have told him but Charlie says that he asked the former landlord to let him do that. Charlie's girlfriend, Tracy Barlow (Kate Ford), is delighted. She thinks, when Charlie tells Keith and Craig that he wants them out, that he intends to live there. Keith decides that he and Craig will move to Sheffield but Craig doesn't want to leave Coronation Street as his girlfriend, Rosie (Helen Flanagan), lives there too. Initially Keith agrees to stay but after an angina attack, he is told by the doctor that it is a warning and things have to change. Keith tells Craig that they are moving to Bournemouth with Keith's sister, Marjorie. Craig is determined that he won't leave the street but Keith and Rosie's mother Sally (Sally Dynevor) persuade him and they leave. Keith later returns to the Street when Craig runs away from Bournemouth and refuses to return there.

In his final scene he punches Danny as he leaves the cobbles. He had previously romanced factory machinist Joanne Jackson (Zaraah Abrahams) as well as Tracy Barlow (Kate Ford), while he also enjoyed a brief flirtation with hairdresser Maria Sutherland (Samia Ghadie) in The Rovers Return Inn.

In July 2009, Freda returned. She revealed to Emily that she was engaged, but her fiancé was in prison.
