Mother's Day is upon us, so we're taking a look at some of the baddest mothers to grace the big and small screen over the years.

These mothers may not always do what's right, but they're doing it for their kids—and if you don't like it, just get out of their goddamn way. Mother is at work.

Here are the 7 baddest mothers of all time.

Mildred Pierce, Mildred Pierce

Though cast as one of the worst mothers of all time by daughter Christina in Mommie Dearest, Joan Crawford portrayed one of cinema’s ultimate matriarchs: the iron-willed Mildred Pierce.

This mother would do anything to appease her spoiled, ungrateful daughter, Veda — short of covering up her murder. After all, there’s only so much a mother can do when her child is probably Satan.

Eleanor of Aquitaine, The Lion in Winter

Katharine Hepburn gives one of her best performances as Eleanor of Aquitaine, mother of Henry II’s (Peter O'Toole) three terrible sons, who are all vying for control of his kingdom.

It’s Christmas and Henry being the softie that he is, lets Eleanor out of prison where he banished her for encouraging her sons to overthrow him. (Like holidays with your family are much better.)

Though she openly doesn’t care for her children, Eleanor still goes out of her way to ensure her favorite, Richard the Lionhearted (Anthony Hopkins) gets the throne.

Beatrix Kiddo, Kill Bill

In a coma for four years, The Bride (Uma Thurman) awakes to find herself no longer pregnant and goes on an epic, blood-soaked revenge mission in Quentin Tarantino's iconic ode to old kung fu movies.

Kiddo slices and dices her way through the fellow assassins who turned their backs on her, finally finding her daughter alive and well and in the care of the titular Bill (David Carradine). So of course, Bill deserved to die and I hope he burns in hell.

Oh, wait, wrong Tarantino film. But the sentiment is in the right place.

Nancy Botwin, Weeds

What's a soccer mom to do when faced when the unexpected death of her husband leaves her penniless to raise three kids by her lonesome? If your Nancy Botwin (Mary-Louise Parker), whatever the hell it takes.

The suburbanite quickly establishes herself as a prominent pot dealer to keep her family in the lifestyle to which they've grown accustomed. But the struggle is real and so is the drug game, as she finds out the hard way, though that doesn't keep her eldest son from joining the family business. The apple bong doesn't fall far from the tree.

Gemma Teller Morrow, Sons of Anarchy

A founding member of the Sons of Anarchy motorcycle gang, Gemma (Katie Sagal) has been a bad bitch from birth. She'll go to any lengths to protect the gang and the perfect ass of her son Jax( Charlie Hunnam).

But when she kills Jax's wife Tara with a fork to the skull, she may have crossed a line.

Jax certainly thought so—he had to avenge his lady by taking out his mama. But thems the breaks when you love too hard.

Cersei Lannister, Game of Thrones

What's a little incest when your brother is the hottest piece this side of the Seven Kingdoms? Sure it's easy to condemn Cersei (Lena Headey) based on her behavior as a sister, but that's neglecting her equally awful behavior as a mother.

Her son Prince Joffrey was kind of the worst but (spoilers) when he's poisoned, she leaves no stone unturned and no shade unthrown in accusing her brother Tyrion for the murder — like any loving, borderline psychotic mother would.

Cookie Lyon, Empire

Like all the mothers on our list, Cookie (Taraji P. Henson) just wants what's best for her children. But that doesn't mean she won't beat the hell out of them with a broom if they don't pay her the respect she's entitled to, Hakeem.

After taking the fall for her husband Lucious (Terrence Howard), and spending 17 years in prison as a result, Cookie returns to claim what's hers — EVERYTHING.

The true mother of all (Cookie) Monsters.

Les Fabian Brathwaite — one bad mother.
