A Convocation (translating ecclesia) is a group of people formally assembled for a special purpose.

In particular it is used to refer to:

• the assemblies of the two Provinces of the Church of England, e.g. the Convocations of Canterbury, and various other assemblies of other churches; and

• A self-governing body of the Church of England. George I dismissed it in 1717, due to it having views opposed to his in the Bangorian controversy. It was the historical antecedent of the General Synod of today.

• the assemblies of various universities which are convoked to grant degrees, etc., and in particular various university legislative assemblies

At the University of Chicago, graduation events are called "convocations," as opposed to commencements, as in other US universities.

In some British and Australian Universities, the term "convocation" refers specifically to the entirety of the alumni of the university, which function as one of the university's representative bodies. Due to its inordinate size, the Convocation will elect a standing committee, which is responsible for making representations concerning the views of the alumni to the university administration. The convocation also, however, can hold general meetings, at which any alumni can attend. The main function of the convocation is to represent the views of the alumni to the university administration, to encourage co-operation among alumni (esp. in regard to donations), and to elect members of the University's governing body (known variously as the Senate, Council, Board, etc., depending on the particular institution, but basically equivalent to a board of directors of a corporation.)

A convocation is also a collective noun for eagles.
