title_body: What are the alcohol free beers?
upvoted_answer: Common brands off the top of my head are:
  
  
  St Pauli N.A.
  O'Doul's
  Kalibur
  Clausthaler
  
  
  There are actually plenty of others, a few of the major brewers like Miller and Coors also produce a non-alcoholic version and a few other German brands you might be able to find come in non-alcoholic.
  
  Be forewarned that none of them are generally regarded as "good" when compared to full-strength beer.
  
  If your interest is just to not get completely obliterated after drinking several beers, I'd investigate a category called "Session" beers, which are regular beers brewed without artificially removing any alcohol but are designed to be flavorful at 3-4% ABV rather than the common 5-6%+ that many craft beers tend to be.  Full Sail session lager, Stone's Go To IPA, and Founder's All Day IPA should be pretty easy to find, but investigate more local and regional breweries to see if they make any.
