We have searched for proton decay via \(p \rightarrow \nu K^{+}\) using Super-Kamiokande data from April 1996 to February 2013, 260 kiloton\(\cdot\)year exposure in total. No evidence for this proton decay mode is found. A lower limit of the proton lifetime is set to \(5.9 \times 10^{33}\) years at 90% confidence level.
