Irina Konstantinovna Feodorova (28 November 1931, Leningrad, USSR – 7 December 2010, Saint Petersburg) was a Soviet historian.

This publication earned Feodorova the honour of being named the "N. N. Miklouho-Macklay Laureate" of the "Presidium of the Russian Academy of Science" in 1981.

The book includes Feodorova's translations of the Easter Island legends recorded in the 1956 manuscripts of the Norwegian researcher Thor Heyerdahl.

Sketches of the culture of the nineteenth and twentieth centuries[4] The book examines the history of the population of Easter Island; the ethnogenesis of its inhabitants; and theories about the original ancient civilisation.

Feodorova analysed the culture of the indigenous people of Rapanui including their folklore, language, chanting connected with string games, features of a tattoo and the stone statues.

[8] In 2001, Feodorova published her attempts at decoding, reading, and translating all the examples of ancient Rapanui text from museums around the world.

Feodorova demonstrates the positive role the missionaries played in Rapanui in the 19th century in the study and preservation of the indigenous population and their culture.

Feodorova's other studies concern the origin of people of Oceania; Pacific oceanic contacts; the role of the Areoi (a society of secret warriors) in Polynesia; the linguistics of Polynesian and American Indian languages.

She has also researched petroglyphs, zodiac signs, ancient calendars, paleoastronomy, toponyms, terms of relationship and social systems, material culture, mythology, religious views, magic fairy tales, games, tattoos and the meanings of Polynesian sculptural and carved images.

[11] Feodorova contributed to the scientific album, Around the world with Krusenstern (2005) and was the co-author in the collective monograph, "Russians in the 'Silent sea'" (2006).
