Yes, all foreign passport holders need a travel visa to India. This can be obtained online. You should look to apply for a travel e-visa. You'll need a passport to do this, and you'll need to pay a fee of about $25. We recommend applying for the travel e-visa at least one month in advance of your flight. The turnaround time tends to be pretty quick (less that 48 hours), but it's better to have extra time in case there's an issue with the application.
