The king of Shringiverapura, a Nishada kingdom on the banks of the Ganga. Rama, who set out on his exile with Sita and Lakshmana, visited Guha who received them and gave them fruits. Rama insisted on only drinking water. He also fed Rama’s horse. At night, when Lakshmana was guarding the Rama and Sita, Guha said he would take on the job. Lakshmana refused but they started talking and thus spent the night. In the morning, as per Rama’s request, Guha took them to the opposite bank on a boat, according to Ramayana Ayodhyakanda Sarga 50.

After Bharata returned from Kekaya and set out looking for Rama, he also visited Guha. Guha updated him and sent a few soldiers with him as per Ramayana Ayodhyakanda Sarga 84.

Agnipurana Chapter 6 also describes Guha’s involvement with Rama, Sita and Lakshmana.
