   It depends on how you define "computer".   
      
   If you include arithmatic mechanisms, then the first would be the abacus   
   from circa 2700 BC.   
      
   The Antikythera mechanism was an analog mechanical device from circa 200   
   BC and was used to predict astronomical positions and eclipses.   
      
   If you mean general purpose mechanical computer, that would be Charles   
   Babbage's Difference Engine, designed in the 1820s.   
      
   The Atanasoff–Berry computer (ABC) was the first automatic electronic   
   digital computer, though it wasn't programmable and was more of an   
   arithmetic logic unit, conceived in 1937.   
      
   The Z3 was an electromechanical programmable, fully automatic digital   
   computer circa 1941.   
      
   The British Colossus was a set of computers and was the first   
   programmable, electronic, digital computer, although it was programmed   
   by switches and plugs.   
      
   The ENIAC was similar to the Colossus and it was Turing-complete though   
   still programmed by patch cables and switches.   
      
   The Manchester Baby, circa 1948, was the first electronic stored-program   
   computer designed as a testbed for random access memory. It was the first   
   working machine to contain all the elements essential to a modern   
   electronic digital computer.   
      
   So if you define "computer" as fully electronic, programmable, digital,   
   Turing-complete and containing electronic memory, the first was the   
   Manchester Baby.
