We present an experimental demonstration of electromagnetically
induced two-photon transparency (EITT) in room temperature
rubidium vapor. The 
to 
fluorescence is used
to monitor the 
to 
two-photon
absorption near resonance with the intermediate state 
.
A controlling pump laser beam is employed to coherently couple
the and 
states, thus producing two dressed
intermediate states which give rise to destructive interference
in the two-photon transition. An induced two-photon transparency
of about 
has been obtained at resonance; our experimental
findings are in good agreement with the general theory of Agarwal
et al. (Phys. Rev. Lett., bf 77 (1996) 1039), when the
appropriate spectroscopic parameters are used.
