Industria de Diseño Textil, S.A. ("Textile Design Industries"), more commonly known as Inditex (English: /ˌɪndɪˈtɛks/), Spanish: [indiˈteks]), is a large Spanish corporation and the world's largest fashion group. It is made up of almost a hundred companies dealing with activities related to textile design, production and distribution. Amancio Ortega, Spain's richest man, and the world's 5th richest man, is the founder and current largest shareholder. The chairman of Inditex is Pablo Isla.

Inditex runs over more than 5402 stores worldwide and owns brands like Massimo Dutti, Bershka, Oysho, Pull and Bear, Stradivarius, Zara, Tempe and Uterqüe, and also a low cost brand Lefties. The majority of stores are corporate-owned; Franchises are only conceded in countries where corporate properties can not be foreign-owned (in some Middle Eastern countries, for example).

The group designs and manufactures almost everything by itself, and new designs are dispatched twice a week to Zara stores.

Inditex headquarters are located in Arteixo, a small industrial town in the metropolitan area of A Coruña, Galicia, in northwestern Spain. Originally almost all merchandise was manufactured there. Now most production has shifted to low-cost labor countries such as Morocco and China. In addition they have another factory mainly responsible for shoe design, production and distribution in Elche, a well-known town of the Alicante province on the Spanish Mediterranean coast.
