Boleyn said

Queen Isabella of Castille, was a formidable woman too she helped drive out the Moors from Castille.
Isabella of France (Commonly called the she wolf) she all but conquerored England.
Queen Hepshepset held Egypt together, for her stepson.
Queen Matilda (Henry 1st daughter) she was a headstrong woman who became very near to being England’s first Queen in her own right..
Eleanor of Aquitaine, an amazing woman simple as that. She worked tirelessly for England although she was a little stubborn and a bit of a trouble maker, but it was she who more or less governed the country when Richard was away, and raised the funds to pay for his ransom, She also made the perilous treck across the Pirenees in the deep cold of winter to take her grandaughter to Castille in her late 70’s. She died at the age of I believe to 82 astonishing age at the time when woman rarely lived past the age of about 35/40.

Oh, I agree, all these women were really strong characters. It’s really hard to pick just one woman to admire! They were all great women! There’s just so many to choose from! Even Elizabeth and Catherine of Aragon would be considered warrior queens.

Here are few more worth mentioning:

The Trung Sisters
After two centuries of Chinese rule, the Vietnamese rose up against them under the leadership of two sisters, Trung Trac and Trung Nhi, who gathered an army of 80,000. They trained 36 women to be generals and drove the Chinese out of Viet Nam in A.D. 40. Trung Trac was then named ruler and renamed “Trung Vuong” or “She-king Trung.” They continued to fight the Chinese for three years, but eventually, unsuccessful, they committed suicide.
Queen Cordelia (on whom the character in Shakespeare’s King Lear is based), battled her nephews for control of her kingdom.
Queen Gwendolen fights her husband Locrinus in battle for the throne of Britain. She defeats him and becomes queen.
Ethelfleda (alternative spelling Aethelfled, Æthelfleda, Æthelflæd) (872/879 – 918), Queen of Mercia, called “Lady of the Mercians”. Daughter of Alfred the Great, she succeeded to Mercian power upon the death of her husband Aethelred, Ealdorman of Mercia (883-911), in 911. She was a skilled military leader and tactician, who defended Mercia against neighboring tribes for eight years.

Can anyone think of any more?

There are a lot of Warrior Queens in mythology and in literature, and I think they should be included! Here is a few of my own:

Andraste, also known as Andrasta or Andred, was, according to the Roman historian Dio Cassius, an Icenic war goddess invoked by Boudica in her fight against the Roman occupation of Britain in AD 60. She may be the same as Andate, mentioned later by the same source, and described as “their name for Victory”: i.e., the goddess Victoria.Thayer asserts that she may be related to Andarta also. The goddess Victoria is related to Nike, Bellona, Magna Mater (Great Mother), Cybele, and Vacuna—goddesses who are often depicted on chariots.

Many Neopagan sources describe the hare as sacred to Andraste. This seems to derive from a misreading of the passage in Dio Cassius in which Boudica releases a hare from her gown:

“Let us, therefore, go against [the Romans], trusting boldly to good fortune. Let us show them that they are hares and foxes trying to rule over dogs and wolves.” When she [Boudica] had finished speaking, she employed a species of divination, letting a hare escape from the fold of her dress; and since it ran on what they considered the auspicious side, the whole multitude shouted with pleasure, and Boudica, raising her hand toward heaven, said: “I thank you, Andraste, and call upon you as woman speaking to woman … I beg you for victory and preservation of liberty.”

The hare’s release is described as a technique of divination, with an augury drawn from the direction in which it runs. This appears to be similar to the Roman methods of divination which ascribe meaning to the directions in which birds fly, with the left side being auspicious and the right side inauspicious. (Sorry, but I had to include a story about Boudica!)

Medb (also: Medhbh, Meadhbh, Meab°, Meabh, Maeve, Maev) is queen of Connacht in the Ulster Cycle of Irish mythology. As recounted in The Cattle Raid of Cooley, she started war with Ulster. For more info on her check out: http://en.wikipedia.org/wiki/Medb

Artemis(Latin Diana) is the Greek goddess of the hunt, daughter of Zeus and Leto and twin sister to Apollo. She is usually depicted bearing a bow and arrows. Artemis was known as the leader and chief goddess of the Amazons. Check out: http://en.wikipedia.org/wiki/Artemis

Athena (Latin: Minerva) is the goddess of wisdom, war strategy, and arts and crafts. Often shown bearing a shield depicting the gorgon Medusa (Aegis) given to her by her father Zeus. Athena is an armed warrior goddess, and appears in Greek mythology as a helper of many heroes, including Heracles, Jason, and Odysseus. Check out: http://en.wikipedia.org/wiki/Athena

Atalanta is one of the few mortal heroines in Greek mythology. She possessed great athletic prowess: she was a skilled huntress, archer, and wrestler, ad was capable of running at astounding speeds. She is said to have participated in the Argonaut expedition, and is one of the central figures in the Calydonian Boar hunt. Atalanta was renowned for her beauty and was sought by many suitors, including Melanion or Hippomenes, whom she married after he defeated her in a foot race. According to some stories, the pair were eventually turned into lions, either by Zeus or Aphrodite. Check out: http://en.wikipedia.org/wiki/Atalanta
