The Undertones reformed in November 1999, initially to play concerts in Derry.
For their reformation, the Undertones replaced Sharkey (who declined to rejoin) with singer Paul McLoone.
Since 1999, the Undertones have performed several tours across the UK, Ireland, Continental Europe, Japan, Turkey and North America and continue to perform live.

Noteworthy gigs by the Undertones since their 1999 reformation include performing at the Glastonbury Festival in June 2005, providing pre-match entertainment prior to kick-off at Celtic Park in the UEFA Champions League play-off between Celtic and Arsenal in August 2009 and, in March and April 2011, performing a series of UK gigs in which they played their debut album, The Undertones, in its entirety as part of each show.
This tour was timed to accompany a re-release of a double compilation album containing all of the A- and B-sides of their singles.

Since their reformation, the Undertones have released two albums of original material with Paul McLoone providing vocals: Get What You Need on 30 September 2003; and Dig Yourself Deep, on 15 October 2007.

In April 2013, the Undertones released their first new material for over five years with the double A-side single "Much Too Late / When It Hurts I Count To Ten."
This single—limited to 1,000 numbered copies—was released as part of the Record Store Day promotion in the UK and was recorded at Toe Rag Studios in London.
