Karreka, daughter of Lyyroq was a female Klingon in the 24th century. She was a member of the House of Krolt before becoming mated to Leskit. With him she had one son, Ch'kan, born 2373.
By 2376, their marriage had become one of convenience only, and Leskit had begun a romantic relationship with Kurak, his shipmate aboard the IKS Gorkon. However, he would not divorce Karreka, as doing so would leave her without a house, and his son without a mother. The situation was resolved when Kurak, upon the death of Moloj, made Karreka the ghIntaq of the House of Palkar. Karreka immediately thereafter ended her marriage to Leskit.
