Natalia Yurievna Ragozina (Russian: Наталья Юрьевна Рагозина; born 5 April 1976), better known as Natascha Ragosina, is an undefeated retired Russian professional boxer who spent much of her career ranked as the top female super middleweight in the world.

Though born in Kazakhstan (formerly a part of the Soviet Union) and currently residing in Moscow, she is the longest reigning WBA female super middleweight champion and WBC female super middleweight champion.

[citation needed] At the time of her retirement, she held all major female super middleweight titles and two heavyweight belts: On 15 March 2008, Ragosina defeated Bermudian Teresa Perozzi to win a record seven championship belts in a single fight.
