Amy Poehler
Amy Poehler may have made this list solely based on her television sketch comedy work, but she also had a short but amazing run on the Upright Citizens Brigade, a show with a small but devoted audience, after her stint at Saturday Night Live, where she proved to be one of the most versatile and consistently great performers to ever grace its stage.
She may have made this list only for her portrayal as Leslie Knope on NBC's Parks and Recreation, where she was one of the nicest, most compassionate, and, of course, funniest employers in television history. It's no accident that this was another of her shows with a devoted following. But, when all of her work is considered, she already ranks among the top ten funniest women in television history, despite the fact that she still has decades to add to her already impressive record. With her comic aptitude, capacity to lead a series, and inherent likability, she might wind up far higher on the list one day.
