The Orange Box is a collection of 5 games from Valve Corp. (They also make Left 4 Dead, which several other people have mentioned on this thread. I still haven't played it yet, though...)

It includes the aforementioned Half-Life 2, HL2:Ep 1, HL2:Ep2 as well as Portal and Team Fortress 2 (which are also pretty awesome games in their own right).

Several of those games were released separately, but at some point, Valve decided that they would release them all together as a compilation.

(Note that it has a 96% Metacritic score...pretty good.)
