Greg Giraldo was just laid to rest in a private family ceremony in The Hamptons ... but last night, tons of Giraldo's famous friends -- including Jon Stewart and Chris Rock -- gathered for a wake in his honor.

Among the famous comics who paid their respects at Giraldo's wake -- Sarah Silverman, Jeff Ross, Bobby Kelly, Jim Norton and Colin Quinn.

And, despite the presence of so many comics -- it wasn't jokey at all  ... the mood was described as "very sad and emotional."

We're also told Colin Quinn delivered a very heartfelt speech about his friend.

As we previously reported, Greg passed away last week at the age of 44. Several of the comic's close friends have set up a fund to support and educate his three young sons.
