Abstract Coffee is one of the plantation commodities with a high economic value among other plantation crops and plays an important role as a source of foreign exchange. Indonesian coffee is classified into two types of coffee, namely arabica coffee and robusta coffee. According to data from the Central Bureau of Statistics of Aceh Province (2019), the area of coffee plantations in Aceh reached 123,749 ha with a production of 68,493 tons. About 85% of the land area is planted with arabica coffee, while the rest is planted with robusta coffee. This study analyzes the morphological relationships of various Arabica and Robusta coffee plant varieties at the Gayo Experimental Garden, Pondok Gajah District, Bener Meriah Regency, Aceh Province. Samples of coffee varieties were selected by purposive sampling method. The morphological characters observed were 25 on stem organs, leaves, flowers, fruits, and beans. Data analysis was conducted using the NTSYS program and presented as a dendrogram. The results showed that eleven coffee varieties were grouped into four groups. The variety that has the furthest kinship is Mocca Yaman, with a coefficient value of 0.58. The varieties with the closest kinship are C 48 and C 49, with a coefficient value of 0.84. These two varieties have similarities in the 19 observed morphological characters.
