Natalia Borisovna Nordman-Severova (Russian: Наталья Борисовна Нордман-Северова; 14 December 1863 – 30 June 1914) was a Finnish–Russian author who was the partner of the artist Ilya Repin.

Repin was captivated by her and they went to live in her home, Penaty, in Kuokkala, which was still part of Finland at that time.

The couple invited notable artists from Russia every Wednesday as their new home was a train ride from St Petersburg.

Nordman's hospitality was well known and visitors included the writers Maxim Gorky and Aleksandr Kuprin; artists Vasily Polenov, Isaak Brodsky, Filipp Malyavin and Nicolai Fechin as well as poet Vladimir Mayakovsky, philosopher Vasily Rozanov and scientist Vladimir Bekhterev.

Nordman left her home to the St Petersburg Academy, which could not take possession immediately, as Repin lived there for 16 more years.
