The launch will see the retailer use Ocado's recently opened distribution centre in Warwickshire for deliveries through a Morrisons-liveried fleet.
The 25-year deal involves Morrisons paying up to £170 million to Ocado to acquire the site and equipment.
This agreement is a significant strategic step for Morrisons.
From a standing start, Morrisons will be competing in the fast-growing online channel by the end of this year with a really compelling proposition.
The customer gets our affordable fresh food delivered by Ocado's state-of-the-art distribution system.
