Letts, also Latvians, a Baltic people. Most Letts live in Latvia, but some live in neighboring areas in Russia, Belarus, Lithuania, and Estonia. They are of neither Germanic nor Slavic origin, but are closely related to the Lithuanians. Physically they resemble other North European peoples, tending to be tall with fair hair and light-colored eyes. Their language is called Lettish (or Latvian). Most Letts are Lutheran. However, there are some who are Roman Catholic or Eastern Orthodox.
The history of the Letts parallels that of Latvia.
