Jassi Jaissi Koi Nahin (transl. There is no one like Jassi) is an Indian soap opera which aired on Sony TV from 1 September 2003 to 4 May 2006.^[1] The series was an Indian-themed version of the Colombian drama Yo soy Betty, la fea.^[2]

Based largely on the show, Yo soy Betty, la fea, the show follows the life of Jasmeet Walia known as Jassi (Mona Singh) who is a plain-looking young woman from a middle-class family in Mumbai. Jassi is a sincere worker and has been working to support her family. She is naive but intelligent. She has always been supported and encouraged by her father, grandmother (Bebe), and her close friend Nandu (Gaurav Gera) but she has faced rejection largely from society simply because of her looks. Jassi somehow lands her dream job at Gulmohur, a big fashion empire. She is appointed as the secretary to Armaan Suri (Apurva Agnihotri) and after a rough start soon becomes indispensable at work. She falls in love with Armaan but keeps her feelings to herself.

The show follows how Jassi becomes successful at Gulmohur but must face difficulties and trouble created by several people unhappy with her success, one of whom is Armaan's arrogant girlfriend Mallika (Rakshanda Khan). She is forced to disappear when things get too murky and is saved by businessman Purab Mehra (Samir Soni) who eventually becomes responsible for Jassi's makeover so she can hide her real identity and avenge the wrongs done to her and her family. Meanwhile, Armaan falls in love with Jassi, and while mourning her disappearance, is inexplicably attracted to her alter ego Jessica Bedi. In the end, Armaan and Jassi unite and gain control of Gulmohur.

Jassi Jaisi Koi Nahi is also known for its remarkable campaigning and marketing done by the channel to attract a huge audience before its launch. The main protagonist 'Jasmeet Walia' was hidden completely from the audience in promotions although the campaigning was focused on the character's uniqueness. This generated a lot of curiosity among its audience to know about the character. This was the first an Indian Television Channel took such a big risk to keep its series protagonist under wraps and still promoting it heavily. The risk paid off and the show opened with a bumper response on its premiere episode. The TV show was well received and it went on to run for three years.^[4]

A special episode aired on 5 March 2005 garnered 10.9 TVR.^[5]
