In the present paper, we consider the nonlocal Kirchhoff problem \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$- \left( {{\varepsilon ^2}a + \varepsilon b\int_{{\mathbb{R}^3}} {|\nabla u{|^2}} } \right)\Delta u + u = Q(x){u^p},u > 0\;\text{in}\;{\mathbb{R}^3}$\end{document}, where a, b < 0, 1 > p > 5} and ǫ < 0 is a parameter. Under some assumptions on Q(x), we show the existence and local uniqueness of positive multi-peak solutions by Lyapunov-Schmidt reduction method and the local Pohozaev identity method, respectly.
