The Co-operative, also known as Co-op, is a brand used by a variety of co-operatives based in the United Kingdom. It is not a single business, but a number of different consumers' co-operatives spanning various sectors.

The Co-operative Group is the largest consumer co-operative in the UK and the biggest user of the Co-operative brand in its 4,500 trading outlets. Many independent retail societies in the UK trade as "Co-op" and others, such as the Central England Co-operative, use the pre-2016 incarnation of the Co-op brand. Most co-operative societies have businesses in many different areas; however, the largest areas of the businesses are in food shops, particularly convenience shops, thus the largest and most visible use of the branding is as Co-op Food.^[1]

The Co-operative brand as it is widely used today came about as a result of the Co-operative Commission's report into the British co-operative movement which recommended that all UK consumers' co-operative societies switch to a universal recognisable co-operative brand. This single brand would be in contrast to the previous array of brands which had existed up to this point including the '1992 cloverleaf', the 'Co-op Welcome' and 'Co-op Late Shop' brands which was understood by the commission to be holding back the public's perception of the co-op sector's modernising approach. Not all of the UK's consumers' co-operative adopted the resultant 2008 and 2016 versions of The Co-operative brand with the Lincolnshire Co-operative and Scotmid being notable examples.

At The Co-operative Group's 2016 AGM, it was announced that the Group would go back to a revitalised version of the 1968 Co-op 'cloverleaf' design, utilising a uniform blue through all business areas.

After the Co-operative Group's 2016 decision to re-adopt the cloverleaf logo, the Midcounties Co-operative took the decision to switch from the Co-operative Brand to the 'coop' Global Cooperative Marque of the International Co-operative Alliance - both in its ventures such as The Phone Co-op and The Co-operative Energy, and in new store openings such as those in Chipping Norton, Bourton-on-the-Water and Bletchingdon.

Membership is crucial to co-operatives and more than 8 million people are members of co-operatives in the UK which use 'The Co-operative Brand'. Members of co-operatives get to be democratically involved in the running of the society, often with votes on key business decisions and for the election of board members. It is also common for members to be provided with a share of the society's annual profits which is proportional to the amount of money that an individual has spent with the society over the year. This share of the profit is commonly referred to as co-op's dividend. The size of the dividend varies depending on the financial performance of the group.

Membership of the majority of consumers' co-operatives in the UK was brought under one identity in 2008 as a part of the launch of 'The Co-operative Brand' however each individual co-operative retains its own individual membership scheme. Members of these societies are given a card which all look very similar but which will list the specific co-op which the individual is a member of on the front. As a part of their membership schemes, many of the larger co-operatives which have adopted 'The Co-operative Brand' will allow members of other co-operatives to earn a share of their profits in a reciprocal agreement. This is particularly the case with those co-ops which have interests in supermarkets, whereas other users of the co-op brand, such as The Phone Co-op operate entirely independent membership schemes.

Because it facilitates democratic engagement with the co-operative and is also a profit sharing mechanism, The Co-operative Membership scheme differs from loyalty cards which many other businesses offer.
