Juana Rosario Arrendel (born 16 June 1978 in La Romana) is a female high jumper from the Dominican Republic.
Arrendel originally won the 1999 Pan American Games in Winnipeg, but lost the gold medal after testing positive for stanozolol.  In 2006 she became the sixth woman to win three Central American and Caribbean Games titles in a row. The other are Miguelina Cobián, Carmen Romero, Bárbara Hechevarría, María Caridad Colón and Letitia Vriesde. 
Her personal best jump is 1.97 metres, achieved in December 2002 at the Central American and Caribbean Games in San Salvador. This is the current Dominican Republic record.
