Abstract: Non-perturbative aspects of the physics of Sp(2N) gauge theories are interesting for phenomeno- logical and theoretical reasons, and little studied so far, particularly in the approach to the large-N limit. We examine the spectrum of glueballs and the string tension of Yang-Mills theories based upon these groups. Glueball masses are calculated numerically with a variational method from Monte-Carlo generated lattice gauge configurations. After taking continuum limits for N = 1, 2, 3 and 4, we extrapolate the results towards large N. We compare the resulting spectrum with that of SU(N) gauge theories, both at finite N and as N approaches infinity.
