Raja Shivaji Vidyalaya (formerly known as King George High School), is a high school in the Dadar neighborhood of Mumbai, India. The school was founded in 1912, and named in honor King George V who had visited India in 1911. It was renamed in 1974, at which time it switched from an English language curriculum to a Marathi curriculum. It has since resumed English education, becoming a "semi-English" (mixed English/Marathi) institution.
In 2012, former President of India, Pratibha Patil was the guest of honor at the school's centenary celebration.
Notable alumni of the school include:
