Tiina Nunnally (born August 7, 1952) is an American author and translator of Norwegian, Swedish, and Danish literature. She also writes her own novels and young adult books.

Nunnally was born in Chicago, Illinois, and grew up in Milwaukee, Wisconsin, and St. Louis Park, Minnesota.

She was an AFS exchange student to Århus, Denmark in 1969 and 1970. In a 2010 interview with Joanne Matzenbacher, Nunnally said that she learned to speak Danish during this time as an exchange student.

She received an MA in 1976 from the University of Wisconsin-Madison and a PhC from the University of Washington in 1979.

She is an affiliate instructor with the Department of Scandinavian Studies at the University of Washington.

Nunnally is a translator of Danish, Norwegian, and Swedish, who sometimes uses the pseudonym Felicity David when edited into UK English. Her translation of Kristin Lavransdatter III: The Cross by Sigrid Undset won the PEN/Book-of-the-Month Club Translation Prize in 2001, and Peter Høeg's Smilla's Sense of Snow won the American Translators Association's Lewis Galantière Prize.

Her first novel, Maija, won a Governor's Writers Award from the State of Washington in 1996. Since then two more of her novels have been published.

The Swedish Academy honored Nunnally in 2009 with a special award for her contributions to "the introduction of Swedish culture abroad".
