The company has secured a supply contract with the Big Four grocer, which will see it offering "hundreds" of Morrisons products through its food delivery service Amazon Pantry and its subscriber service Amazon Prime Now.
The deal will give Amazon customers access to Morrisons "fresh and frozen" products, the supermarket said.
Morrisons chief executive David Potts said the combination of the supermarket's "fresh food expertise and Amazon's online and logistics capabilities is compelling".
He added: "This is a low-risk and capital-light wholesale supply arrangement that demonstrates the opportunity we have to become a broader business."
The announcement comes after supermarket Sainsbury's upped the ante in the highly-competitive grocery sector last month when it tabled a £1.3 billion bid for Argos-owner Home Retail Group in an attempt to become a ''world-leading'' retailer bigger than John Lewis and Amazon UK.
