In this paper we have proposed an almost unbiased ratio and product type exponential estimator for the finite population mean Y-bar. It has been shown that Bahl and Tuteja (1991) ratio and product type exponential estimators are particular members of the proposed estimator. Empirical study is carried to demonstrate the superiority of the proposed estimator.
