How many crowned queens of England/Britain have there been?

There have never been monarchs of Britain of either sex, they are monarchs of the United Kingdom.

Lady Jane Grey was NOT queen. The CORRECT answer is 6.

Turnip, you are half correct. Jane was indeed never crowned but Anne was Queen in her own right. Mary 11 was joint monarch with her husband

Grey never crowned

Actually Lady Jane grey and Anne were not crowned queens. they only had queen in their title because they were married to the king.

grey was de facto queen but no coronation and thus not a crowned queen

Badly let down by group choice!
