Countess Natalia Kirillovna Zagryazhskaya (née Razumovskaya; 5 September 1747 – 19 May 1837) was a Russian philanthropist, salonist and lady-in-waiting.
She was a leading member of Saint Petersburg society from the 1770s until her death in 1837 and is often mentioned in contemporary memoirs and diaries.
In 1762 she became a lady-in-waiting to Empress Catherine the Great, and – in contrast to other ladies-in-waiting – was allowed to live at home.
A frequent host of members of the Imperial family, she was known as a contact person who could successfully ask them for favours on others' behalf.
The poets Vasily Zhukovsky, Pyotr Vyazemsky and Alexander Pushkin were guests at her salon.
