Gide Loyrette Nouel is an independent French law firm. It is one of the rare international leading law firms to have originated in continental Europe rather than the UK or USA. Though Pierre Gide's legal practice began as early as 1920, the firm was itself founded in 1957 by Gide, Jean Loyrette and Philippe Nouel after the Paris Bar amended its rules allowing lawyers to form associations and practice in a collective. It numbers more than 600 attorneys and legal consultants, including 100 partners, covering 40 different nationalities. The firm operates as a limited liability partnership in London and as its French equivalent, an association d'avocats à  responsabilité professionnelle individuelle (A.A.R.P.I.) in France.

The firm is organised into international practice groups, covering the following practice areas: Banking & Finance; Competition & International Trade; Dispute Resolution; Employment; Insurance, Industrial Risk & Transport; Intellectual Property & Telecommunications, Media and Technology (TMT); Mergers & Acquisitions / Corporate Law; Projects (Finance & Infrastructure); Public Administrative Law; Real Estate; Tax.
