  We use the extended uncertainty principle (EUP) in order to obtain the
R\'{e}nyi entropy for a black hole (BH). The result implies that the
non-extensivity parameter, appeared in the R\'{e}nyi entropy formalism, may be
evaluated from the considerations which lead to EUP. It is also shown that, for
excited BHs, the R\'{e}nyi entropy is a function of the BH principal quantum
number, i.e. the BH quantum excited state. Temperature and heat capacity of the
excited BHs are also investigated addressing two phases while only one of them
can be stable. At this situation, whereas entropy is vanished, temperature may
take a non-zero positive minimum value, depending on the value of the
non-extensivity parameter. The evaporation time of excited BH has also been
studied.
