Simuka (Brahmi:𑀲𑀺𑀫𑀼𑀓, Si-mu-ka) was an Indian king belonging to the Satavahana dynasty. He is mentioned as the first king in a list of royals in a Satavahana inscription at Nanaghat. In the Puranas, the name of the first Andhra (Satavahana) king is variously spelt as Shivmukha, Sishuka, Sindhuka, Chhismaka, Shipraka, Srimukha, etc. These are believed to be corrupted spellings of "Simuka", resulting from copying and re-copying of manuscripts. Based on available evidence, Simuka cannot be dated with certainty. According to one theory, he lived in 3rd century BCE; but he is generally thought to have lived in the 1st century BCE. Epigraphical evidence strongly suggests a 1st-century BCE date for Simuka: Simuka seems to be mentioned as the father the acting king Satakarni in the Naneghat inscription dated to 70-60 BCE, itself considered on palaeographical grounds to be posterior to the Nasik Caves inscription of Kanha (probably Simuka's brother) in , dated to 100-70 BCE. Recent analysis of sources puts Simuka's reign possibly around 120 - 96 BCE. According to the Puranic lists of future kings, "137 years after the accession of Chandragupta Maurya, the Sungas will rule for 112 years and then the Kanvayanas for 45 years whose last king Susharman will be killed by the Andhra Simuka". If the accession of Chandragupta Maurya is dated to 324 BCE, then Simuka started to rule 294 years later, in 30 BCE. Simuka is mentioned as the first king in a list of royals in a Satavahana inscription at Naneghat. The various Puranas have different names for the founder of the Andhra dynasty: Shishuka in Matsya Purana, Sipraka in Vishnu Purana, Sindhuka in Vayu Purana, Chhesmaka in Brahmanda Purana, and Shudraka or Suraka in Kumarika Khanda of Skanda Purana. These are believed to be corrupted spellings of Simuka, resulting from copying and re-copying of manuscripts. The Matsya and Vayu Puranas mention that the first Andhra king overthrew the Kanva king Susharman (c. 40–30 BCE). Based on identification of Simuka with this king, some scholars believe that Simuka's reign started in 30 BCE.
