Udai Singh II (August 4, 1522 – February 28, 1572) was the Maharana of Mewar and the founder of the city of Udaipur in the present day Rajasthan state of India. He was the 53rd ruler of the Mewar Dynasty. He was the fourth son of Maharana Sangram Singh (Rana Sanga)  and Rani Karnavati, a princess of Bundi.He had 3 wives Rani Jaivantabai, Rani Sajja and Rani Dhirbaiji .He had three sons Rana Pratap, Shakti Singh and Sagar Singh .
Udai Singh was born in Chittor. In August, 1522. after the death of his father, Maharana Sangram Singh, he was succeeded by his eldest surviving son, Maharana Ratan Singh. Ratan Singh was assassinated in 1531. He was succeeded by his brother Maharana Vikramaditya Singh. During his reign, when the Turkic Sultan of Gujarat Bahadur Shah sacked Chittor in 1534, Udai Singh was sent to Bundi for safety. In 1537, Banbir killed Vikramaditya and usurped the throne. He tried to kill Udai Singh also, but Udai's nurse Panna Dhai sacrificed her own son to save him from his uncle Banbir and took him to Kumbhalgarh. She did not ask for anything in return either. She started living in Bundi and did not allow Udai Singh to come and meet her. He lived in secret in Kumbhalgarh for two years, disguised as a nephew of the governor Asha Shah Depura(Maheshwari).
In 1540, he was crowned in Kumbhalgarh by the nobles of Mewar. His eldest son Maharana Pratap from his first wife, Maharani Jaivantabai Songara, was born in the same year. He had twenty wives and twenty-five sons. His second wife, Sajjabai Solankini gave birth to his son Shakti and Vikram Dev. Dheerbai Bhattiyani was his favourite wife and was the mother of his son Jagmal Singh.
In 1562, he gave refuge to Baz Bahadur of Malwa. Using this as a pretext, Akbar attacked Mewar in October,1567. On October 23, 1567 Akbar formed his camp near Udaipur. According to Kaviraj Shyamaldas, Udai Singh called a council of war. The nobles advised him to take refuge along with the princes in the hills, leaving a garrison at Chittor. Udai Singh retired to Gogunda (which later became his temporary capital) leaving Chittor in the hands of his loyal chieftains Jaimal and Patta. Akbar captured Chittor after a long siege on February 25, 1568. He later shifted his capital to Udaipur. He died in 1572 in Gogunda. Before his death, he nominated his fifth son Jagmal as his successor under the influence of his favourite queen and Jagmal's mother Rani Bhattiyani. But after his death, the nobles of Mewar prevented Jagmal from succeeding and placed Maharana Pratap Singh on the throne on March 1, 1572.
