Laima, deriving her name from the Lithuanian word laimė meaning "happiness" or "luck," is a central figure in Baltic mythology, revered as the goddess of fate and fortune.

Predominantly worshipped in Latvia and Lithuania, she plays a crucial role in the life cycle of individuals, from birth to death, marriage, and even the fate of crops and animals. Laima's influence permeates daily life, particularly in matters of fortune, well-being, and success.

Closely associated with the sacred linden tree, Laima often appears alongside Dievs, the sky god, and Saule, the sun goddess, forming a divine trio governing human destiny. Her presence is particularly significant during childbirth, when she pronounces each infant's destiny. She also arranges marriages, oversees weddings, and protects pregnant women, ensuring life's continuity and societal harmony.

In Latvian mythology, Laima sometimes forms part of a trinity of fate deities with her sisters Kārta and Dēkla. While all three have similar functions, Laima governs luck and childbirth, Dēkla oversees children, and Kārta influences adult life.

Her role extends to the natural world, influencing field fertility and animal well-being, particularly horses. This multifaceted role offers insight into Baltic cultural values, emphasising the interconnectedness of fate, nature, and human existence.
