The top quark is the most massive known fundamental constituent of matter.Its unexplained large mass suggests a connection to the still mysterious electroweak symmetry breaking mechanism and a rich set of links are postulated between final states with top quarks and possible new particles and interactions that can manifest themselves at the Large Hadron Collider. Top/anti-top pairs are expected to be abundantly produced at the LHC (even at an energy of 7 TeV ) and they will play a major role in detector commissioning. Finally top/anti-top pairs also represent a major background to most searches for new physics at the LHC.A review will be presented on the latest measurements involving top quarks performed by the ATLAS detector at the Large Hadron collider using the dataset collected in 2010.
