Abstract.In this paper, it is shown that Generalized Hardy-Hilbert's double series inequality with weights can be established by introducing a parameter $ \lambda $ ( $ 1 - \textstyle{q \over p} < \lambda \le 2) $ and two positive and differentiable functions $ u\left( x \right) $ and $ v\left( x \right) $ in interval (0, +  $ \infty ) $. In particular, for case $ p = 2 $, the various new extensions of the classical Hilbert's inequality for double series are obtained. As applications, some important inequalities are built, when $ u\left( x \right) $ and $ v\left( x \right) $ are power function, logarithm function, inverse trigonometric function and exponent function.
