Gandi SAS (Gestion et Attribution des Noms de Domaine sur Internet – "Management and Allocation of Domain Names on the Internet") is a French company providing domain name registration, web hosting, and related services. The company's main office is in Paris.

Gandi was founded as a domain registrar in April 2000 by Valentin Lacambre, Laurent Chemla, Pierre Beyssac and David Nahmias.

In 2005 following internal struggles in management, ownership and management of Gandi was sold to a team led by Stephan Ramoin (formerly of MultiMania/Lycos), and investors Joe White, Eirik Pettersen (co-founders of the online website building service Moonfruit), and Warren Stephens.

In 2008, Gandi launched a Xen-based VPS cloud hosting service, based on a system of "shares" and scalable resources that can be adjusted in real time.

In 2010 the company created a subsidiary in the US, opening a data center in downtown Baltimore, Phoenix, Arizona and business offices in San Francisco, California, as well as creating a customer support center in the US, which until then had been exclusively operated out of Paris, France at Place de la Nation.

In late 2011, Gandi.net was the 25th largest registrar in terms of the number of domains registered.

On 31 July 2014, Amazon Web Services partnered with Gandi and announced the ability to register domains directly through their Route 53 Service.

On 28 February 2019, Gandi CEO Stephan Ramoin announced that private equity firm Montefiore Investment had acquired the company.
