Baltic Tiger is a term used to refer to any of the three Baltic states of Estonia, Latvia, and Lithuania during their periods of economic boom, which started after the year 2000 and continued until 2006–2007. The term is modeled on Four Asian Tigers, Tatra Tiger, and Celtic Tiger, which were used to describe the economic boom periods in East Asia, Hungary, Serbia, Slovakia, and Ireland, respectively.

The Four Asian Tigers are the developed Asian economies of Hong Kong, Singapore, South Korea, and Taiwan. Between the early 1950s and 1990s, they underwent rapid industrialization and maintained exceptionally high growth rates of more than 7 percent a year.
