Junior Rotter was a fictional character who had his own strip in the British comic Whizzer and Chips, and later in Buster when the two comics merged in 1990. The strip was about a boy called Junior Rotter (or J.R.) who is always scheming up plans which generally fail. The character is loosely based on the character of the same name from the television soap opera Dallas. His sister in the comic strip was called Sue Helen who, in contrast to her brother, was a decent, charming and helpful person. Being chalk-and-cheese characters meant that JR and Sue Helen's sibling rivalry extended into all-out conflict. When Buster ended, the last issue had a page where all the ultimate fate of the characters was shown: J.R was shown as becoming Prime Minister.

A similar strip, also loosely based on J. R. Ewing from Dallas, called Jay R Hood appeared in rival publisher DC Thomson's Nutty coincidentally this strip also featured a character called Sue Helen who acted as Jay R's most common victim.

Junior Rotter was drawn by Trevor Metcalfe.
