He told the crowd he started on a daytime soap at NBC's 30 Rock and now, he's on "30 Rock."
"Even though I've done a lot of different things in film - big films, little films - plays, so forth. The television show that I'm doing now really has been the best experience I've ever had," said Baldwin.
"Will and Grace" co-star Megan Mullally, "30 Rock" co-star Jack McBrayer and Baldwin's younger brother, Stephen, joined him at the ceremony in front of the Beso restaurant on Hollywood Boulevard.
Since 2006, Baldwin has portrayed network executive Jack Donaghy on "30 Rock," receiving four Emmy nominations as outstanding lead actor in a comedy and two Emmys.
His film credits include "It's Complicated," "Glengarry Glen Ross," "The Aviator," "The Hunt for Red October," "The Shadow," "Beetlejuice," "Miami Blues," "Ghosts of Mississippi," "The Cat in the Hat" and "The Departed."
