Erikka is of Scandinavian origin, derived from the Old Norse name Eiríkr, which was composed of two elements: 'ei', meaning 'always', and 'ríkr', translating to 'rich'. Thus, Erikka signifies 'always rich' or 'ever powerful'. It's a unisex name, often used for girls in various cultures today. Erikka is pronounced /EH-rih-kuh/, with the emphasis on the first syllable. Spelling variations include Erika and Eirica. The name gained popularity during the late 20th century, likely due to its association with notable figures like Swedish tennis player Björn Borg's wife, Mariana "Mimmi" Borg née Erikka Lundgren.
The name Erikka experienced significant popularity during the late 1960s to mid-1980s, with a peak of 37 births in 1987. After this period, its usage declined steadily, reaching single digits by the early 2000s and averaging around 5 births per year since then. In total, there have been 981 births named Erikka from 1967 to 2010.
