Anastasija Steinbeck, née Ryzhikh (born 19 September 1977 in Omsk) is a Russian-born German pole vaulter.

After living in Russia as a child, father Vladimir Ryzhikh moved his family to the German city of Ulm in 1992.

[citation needed] Soon, his elder daughter "Nastja", as she was then called, flourished in this sport (like her younger sister Lisa Ryzih later), setting several junior records and participating for Germany after obtaining German citizenship when she was 18.

For her German passport, her first name was transcribed in German ("Настя" = "Nastja"; "Nastya" in English transcription) and her family name in French ("Рыжих" = "Ryjikh"; "Ryzhikh" in English transcription) Ryzhikh's greatest success was the gold medal in the 1999 world indoor championships in Maebashi.

In 2000, she made headlines when she posed nude for the German Max lifestyle magazine.
