The results of a search for eclipsing Am star binaries using photometry from the SuperWASP survey are presented. The light curvesof 1742 Am stars fainter than V = 8.0 were analysed for the presence of eclipses. A total of 70 stars were found to exhibit eclipses,with 66 having sufficient observations to enable orbital periods to be determined and 28 of which are newly identified eclipsingsystems. Also presented are spectroscopic orbits for 5 of the systems. The number of systems and the period distribution is found tobe consistent with that identified in previous radial velocity surveys of ?classical? Am stars.
