Lucia Peka (March 30, 1912 – August 13, 1991) was a Latvian-American artist.
Born in Latvia, she became part of the diaspora of artists who fled Latvia during World War II, and eventually settled in the United States where she was a successful painter of landscapes, figures, and still life for almost 50 years.
A touring gallery collection travelled within the US Midwest and Washington, D.C.(2010–2011) exhibiting a collection of Peka oil paintings along with other Latvian Displaced Persons of the mid 20th century.
