Celma da Graça Soares Bonfim (born 23 December 1977) is a Santomean long-distance runner. Da Graça represented São Tomé and Príncipe at the 2008 Summer Olympics in Beijing, where she carried the nation's flag for her team during the opening ceremony. She ran in the first heat of the women's 5000 metres, against fifteen other athletes, including Ethiopia's Tirunesh Dibaba, who eventually won the gold medal in this event. She finished the race in last place by more than forty seconds behind Malawi's Lucia Chandamale, with her personal best and national record-breaking time of 17:25.99. Da Graça, however, failed to advance into the semi-finals, as she placed thirtieth overall, and was ranked farther below six mandatory slots for the next round.
