The purposes of this study are to examine the influence of environmental information disclosure and financial performance on stock returns of Indonesian mining companies listed on Indonesia Stock Exchange (IDX) period of 2011-2015. This study is a correlational study with total samples of 145 companies. Secondary data used from Indonesia Stock Exchange. The samples in this research are mining companies using purposive sampling techniques. The findings in this study, there was a simultan effect between environmental information disclosure, financial performance and stock returns. Partially, it is found that environmental information disclosure and financial performance (profitability) positively influence stock returns, while there was no significant influence between financial performance (liquidity) and stock returns. Thus, in addition to providing evidence on the association between voluntary disclosure and firm performance (stock returns), our results highlight the benefit of parsing broader measures (e.g. voluntary environmental disclosure) when examining complex relationships.
