  This is an overview of top quark search, with particular emphasis on the more
recent results. After a brief introduction to the basic constituents of matter
and their interactions, I shall discuss the indirect evidences for the
existence of top quark and its mass from LEP and finally the direct observation
of a top quark signal recently reported from the Tevatron collider. I shall try
to put these results in perspective and provide some insight into the physics
issues involved in the top quark search.
