In this Letter we show that pseudoscalar meson leptonic decay data can be used to set stringent limits on the mass m_{W_{R}} of a right-handed vector boson, such as the one that appears in left-right symmetric models. We have shown that for a heavy neutrino with a mass m_{N} in the range 50<m_{N}/MeV<1900 one can constraint m_{W_{R}}≳(4-19) TeV at 90% CL. This provides the most stringent experimental limits on the W_{R} mass to date for this heavy neutrino mass range.
