Sivamaka Sada (b. n.d.; d. n.d.) was a ruler of the Sada dynasty, which governed a part of present-day Andhra Pradesh from the first century BCE to the first century CE. He is likely to have been the last Sada ruler, before the emergence of the Satavahana dynasty in the region. His reign is speculated to have spanned c. 75–100 CE. Previously, he was considered a Satavahana ruler, however, numismatical evidence has led historians to believe that the Sadas may have been an independent local dynasty.
