This is not a simple question believe it or not. By biggest you probably mean 'Most Massive'. Mass or weight is a better indication of size than say length or height.
The biggest known dinosaurs belong to the group sauropoda (commonly known as the long necks).
Annoyingly the biggest known dinosaurs are also some of the least complete, often only known from a few bones. It's is not easy to list them in any order because of the uncertainties as to their exact size.
Some of the biggest dinosaurs include (no particular order): Amphicoelias, Argentinosaurus, Futalognkosaurus, Puertasaurus, Antarctosaurus, Paralititan, Brachiosaurus, Giraffatitan, Sauroposeidon, Turiasaurus and Supersaurus.
The longest was Seismosaurus it was 50 meters long, weighed 100 tons and its name means The Earthquake lizards. The tungeset was Amphicoelias it weighed 125 tons, was 40 meters long and its name means Doubly Hollow.
