The Siddhivinayak Temple is a Hindu temple dedicated to Lord Ganesh, located in Mumbai, India. It was not built by a single individual; rather, it was constructed over time by various devotees and philanthropists.

The original Siddhivinayak Temple was built in 1801 by Laxman Vithu and Deubai Patil. The couple, who were childless, decided to construct the temple dedicated to Lord Ganesha, and after the completion of the temple, they found their wishes fulfilled. Over the years, the temple has undergone renovations and improvements with contributions from different individuals and organizations. The Siddhivinayak Temple is now one of the most famous and revered temples in Mumbai, attracting a large number of devotees.
