We present several generating functions for sequences involving the central binomial coefficients and the harmonic numbers. In particular, we obtain the generating functions for the sequences $\binom{2n}{n} H_{n} $, $\binom{2n}{n} \frac{1}{n} H_{n} $, $\binom{2n}{n} \frac{1}{n+1} H_{n} $ , and $\binom{2n}{n} n^{m} $. The technique is based on a special Euler-type series transformation formula.
