Porang is an agricultural commodity with high economic value recently. However, the high economic value does not have much impact on farmers due to low added value and market share. This study aimed to analyse the added value and market share of the porang value chain in Wonogiri regency. Cost, and marketing margin were examined to determine each actor’s added value and market share in the chains of Porang in Wonoiri. Data was collected through interviews with all chain actors, such as farmers, rural collectors at the village and district level, wholesalers, and processors. The results show that the highest added value and market share of Porang is in a processor, with 97.88% and 95.14%, respectively. While the lowest one is in farmers, there are no added value activities, and the market share is 5.84%. There is a big gap in added value and market share among actors in the Porang value chains. Strategies to upgrade velue chains at farmer level are to upgrade governance structures, added value activities, and network structures.
