Yes, he is. Under British law, a commoner is anybody who is neither the Sovereign (ie. the reigning queen or king) nor a peer. Prince Harry, is currently neither.
When his brother Prince William was married, he (William) was given the title Duke of Cambridge (ie. a peerage) and as such ceased to be a commoner.
Harry, however, remains a commoner.
By the way, commoner is not to be confused with the pejorative British term 'common' which refers to a person who is brash, vulgar and unrefined.
(on edit) The above answer is totally untrue!!! Prince Henry (Harry) is NOT a commoner. He is a Royal Prince. So was (and still is) Prince William. Where do people get these stupid answers from????
(further edit for clarification)
The Oxford English Dictionary defines commoner as, among other things, someone who is not part of the aristocracy or royalty. Prince Harry (Henry Charles Albert David, or Prince Henry of Wales) does not fit under this definition of commoner, and OED contains a highly reputable collective of researchers.
Keep in mind, too, that royalty experts worldwide prefer to avoid the word commoner as it has dropped out of favor of official British law. See the related links below for more details.
Prince William married Miss Catherine Middleton (a commoner) on 29 April 2011. In British law, strictly speaking, a commoner is anyone who is neither the monarch (King/Queen) nor a peer (Duke, Marquess, Earl, Viscount or Baron/Lord.) Prince William was a commoner before he was made a Duke; Prince Harry still is a commoner.

A commoner.
When a commoner marries royalty, it is often referred to as a "commoner-royalty marriage" or simply a "royal marriage." In some contexts, it may also be called a "commoner marrying into royalty." These unions can attract significant public interest and often come with various social implications and changes in the commoner's status. Examples include Prince Harry's marriage to Meghan Markle and King Edward VIII's marriage to Wallis Simpson.
