  In this paper we obtain the entropy formula of black hole solutions of
Minimal Massive Gravity (MMG) by Tachikawa method \cite{a}. Then we apply this
formula for BTZ black hole solution. We find that the usual Bekenstein-Hawking
entropy is modified. The modification come from Chern-Simons (CS) term and new
term in MMG. The contribution of CS term, which is proportional with inner
radius of horizon is not new, but last term which is due to the new term of
MMG, as usual is proportional to the outer radius of horizon and is new result.
Then we show that the total entropy exactly can be reproduced by Cardy formula
for entropy of the dual boundary CFT.
