  New CCD photometry of NGC 6366 has lead to the discovery of some variable
stars. Two possible Anomalous Cepheids (or Pop II Cepheids), three long period
variables, one SX Phe and one eclipsing binary have been found. Also a list of
10 candidate variables is reported. The light curve of the RRab star, V1, has
been decomposed into its Fourier harmonics, and the Fourier parameters were
used to estimate the star's metallicity and distance; [Fe/H] = -0.87 +- 0.14
and d = 3.2 +- 0.1 kpc. It is argued that V1 may not be a member of the cluster
but rather a more distant object. If this is so, an upper limit for the
distance to the cluster of 2.8 +- 0.1 kpc can be estimated. The P-L
relationship for SX Phe stars and the identified modes in the newly discovered
SX Phe variable, V6, allow yet another independent determination of the
distance to the cluster of d = 2.7 \+- 0.1 kpc. The M_V - {\rm [Fe/H]}
relationship for RR Lyrae stars is addressed and the case of V1 is discussed.
