Simba Wanyika was a Kenyan based band created in 1971 by Tanzanian brothers Wilson Kinyonga and George Kinyonga, and disbanded in 1994. Simba Wanyika and its two offshoots, Les Wanyika and Super Wanyika Stars, became some of the most popular bands in Kenya. Their guitar-driven sound, inspired by the Soukous guitarist Dr. Nico, combined highly melodic rumba with lyrics sung in Swahili. Simba wa nyika means "Lions of the Savannah" in Swahili.

Wilson Kinyonga and George Kinyonga began as musicians in their hometown Tanga in Tanzania when they joined Jamhuri Jazz Band in 1966. They moved to Arusha in 1970 and formed Arusha Jazz with their other brother, William Kinyonga. During this period, musicians could travel freely between Kenya and Tanzania, and Kenyan popular music became heavily influenced by Tanzanian rumba musicians. In 1971 the Kinyonga brothers moved to Kenya and created Simba Wanyika. The band played at nightclubs and bars in the Nairobi area, and developed an enthusiastic following, and by the mid 1970s, they were well known throughout Kenya, thanks to hits like "Mwongele" and "Wana Wanyika". They had a harder sound than most rumba bands and were almost unchallenged in that area in Kenya due to the closing of the Tanzanian border in 1977.
