The purpose of this paper is to construct height pairings for algebraic cycles, generalizing the known cor:; truction for O-cycles and divisors. Let X be a smooth projective variety of dimension d defined over a number field k. For ps d, let M (X)(resp. AJX)) denote the group of algebraic cycles of codimension p (resp. dimension p) on X defined over k, cohomologous to 0 in@‘(Xk, Q,)(resp. H2d-2p) 9 taken modulo rational equivalence. We will be working with#‘(X)@ Q, so questions of torsion will not arise and we may if we like consider rational equivalence on Xk. Ideally we would want a pairing
