Having previously confirmed shows at the Aviva Stadium on 28 and 29 June next year, Swift will now take to the stage at the venue on June 30, along with 13 further dates across Europe.
Tickets will go on sale from July 20.
Confirming this, Taylor Swift tweeted, "Really can't contain my excitement because… we’re adding 14 new shows to The Eras Tour. And I get to travel the world doing shows with @paramore!!.
"Hayley and I have been friends since we were teens in Nashville and now we get to frolic around the UK/Europe next summer??? I’m screaming???".
This marks Taylor Swift's first World Tour since 2018, a year which saw her release four studio albums, including her Grammy Award winning album 'Folklore'.
