Swietenia macrophylla King. is an exotic species from Latin America which have been planted in Indonesia since 1870. This species is a good wood source for construction timber which is quite important in Indonesia. This study was conducted to determine the effect of seed source and family on S. macrophylla seedling growth which may be useful for supporting breeding program of this species. The seeds were collected from four seed sources: Banjar - West Java, Samigaluh - Kulonprogro, Bondowoso - East Java and Lombok – West Nusa Tenggara. Every seed source consisting of 10 families, except Bondowoso which had 5 families. The study was arranged in a randomized complete design, five seedlings per plot and repeated 5 times for each family. At 7 months old the seed source had significantly influence on height and stem diameter, while the family significantly influence height, stem diameter and the number of leaf. Banjar seed source had the best height growth (55.8 cm), while Banjar and Lombok seed sources had the best stem diameter, respectively 0.62 cm and 0.61 cm.
