Paho, also spelled Pahu, is a village in Khiron block of Rae Bareli district, Uttar Pradesh, India. It is located near the road from Raebareli to Mauranwan and Unnao, close to the border with Unnao district. It is 18 km away from Lalganj, the tehsil headquarters. As of 2011, Paho has a population of 5,620 people, in 1,088 households. It has two primary schools and no healthcare facilities, and it hosts a weekly haat but not a permanent market. It is the seat of a nyaya panchayat which also includes 7 other villages.

Paho was historically the seat of a taluqdari estate belonging to a branch of the Bais Rajputs, and the ruins of two old Bais forts are present in the village. One is close to the village, while the other is near the southwestern corner of the village lands.

According to oral tradition, Paho was founded sometime around 1100 CE. It later became the seat of a taluqdari estate belonging to a branch of the Saibasi clan of the Bais Rajputs. The Paho taluqa was founded by Mitrajit Singh, one of the eight sons of Rana Doman Deo of Chiloli. Mitrajit Singh accompanied Aurangzeb on a military expedition to Kandahar and was killed in an avalanche in 1647. Mitrajit Singh's ninth-generation descendant, Bhup Singh, lost possession of most of the taluqa's villages. At the time of the British summary settlement in 1856, Paho itself was assigned to the Gautam cultivators, although it was restored to the Bais in 1859 with the Gautams as under-proprietors. By the turn of the century, the Paho taluqa consisted of five villages and three pattis in the pargana of Khiron, one village each in the parganas of Sareni and Dalmau, and one mahal in the pargana of Raebareli. The taluqdar also held the Gulariha estate of five villages in Unnao district.
