Dorothy aka Dot from season 5 of fargo was fantastic imo!
Ellen (and I guess some would argue Jo) from supernatural is imo. WIthout going into spoilers but the reason I pick her out of a series full of "badass women" is she is the typical tough lady superficial stuff but also extremely compassionate, a supportive and devoted mother.
Does Leslie Knope parks and rec count? She's a badass to me.
