George Shoobridge Carr (1837–1914) was a British mathematician.
He wrote Synopsis of Pure Mathematics (1886).
This book, first published in England in 1880, was read and studied closely by mathematician Srinivasa Ramanujan when Ramanujan was a teenager.
He had already produced many theories at the age of 15.
Carr was a private coach for the Tripos mathematics examinations at the University of Cambridge, and the Synopsis was written as a study guide for those examinations.
