Connolly's observational comedy is idiosyncratic and often off-the-cuff.
He has offended certain sectors of audiences, critics and the media with his free use of the word "fuck" and he has made jokes relating to masturbation, blasphemy, defecation, flatulence, haemorrhoids, sex, his father's illness, his aunts' cruelty and, in the latter stages of his career, old age (specifically his experiences of growing old).

In 2007 and again in 2010, he was voted the greatest stand-up comic on Channel 4's 100 Greatest Stand-Ups.
He once again topped the list on Channel 5's Greatest Stand-Up Comedians, broadcast on New Year's Eve 2013.

Since the 1980s, Connolly has worn a custom-made black T-shirt with a shirt-tail as part of his on-stage attire.
From 1986 until his death in 2017, his manager was Steve Brown.
