The Sri Kalyana Venkateswara Temple in Srinivasa Mangapuram, located in the Chittoor district of Andhra Pradesh, is a significant Hindu temple dedicated to Lord Venkateswara, a form of Vishnu. The temple is considered sacred and is often visited by devotees who are unable to make the journey to the more famous Venkateswara Temple in Tirumala.

According to legend, after marrying Goddess Padmavathi, Lord Venkateswara stayed at the ashram of sage Agastya for six months before continuing his journey to Tirumala. The temple is especially significant for newlywed couples, who often visit to seek blessings for a happy married life.

The temple is maintained by the Tirumala Tirupati Devasthanams (TTD) and is recognized as an Ancient Monument of National Importance by the Archaeological Survey of India (ASI). The temple hosts various utsavams (festivals) and rituals throughout the year, with the Annual Sakshatkara Vaibhavotsavam being one of the most important celebrations.
