Emilia Tabalanza Boncodin (25 May 1954 – 15 March 2010) was a former secretary of the Department of Budget and Management (DBM) and an educator. She was among the 10 members of President Gloria Macapagal-Arroyo's Cabinet, known as the Hyatt 10, who resigned in 2005 at the height of the alleged 2004 election-rigging controversy dubbed the “Hello, Garci” Scandal.
Boncodin was born in 1954 in Iriga City, Camarines Sur. She was valedictorian of her class in both Iriga Central Pilot School and St. Anthony College. She later attended the University of the Philippines (UP) as a government scholar and graduated with a bachelor's degree in business administration and accountancy in 1975. In the same year, she passed and ranked 15th in the Certified Public Accountant Board Examination administered by the Professional Regulation Commission. Boncodin went to Harvard University as an Edward S. Mason Fellow at the Kennedy School of Government and earned her master's degree in public administration in 1986.
Boncodin first joined DBM in 1978 as a senior fiscal planning specialist. She was promoted to division chief and soon became the director of the then Office of Budget and Management. She served as officer-in-charge of the Government Corporations Budget Bureau under DBM when it was reorganized, later before becoming an assistant secretary of the department in 1989. She was appointed DBM undersecretary in 1991.
In 1998, former President Fidel V. Ramos appointed her as budget secretary but her stint was cut short by the designation of Benjamin Diokno during President Joseph Estrada's term. In 2001, Arroyo reappointed Boncodin; however, the budget secretary issued her resignation in 2005.
While serving as a government official, Boncodin was also a professor at the UP National College of Public Administration and Governance and a lecturer at Ateneo de Manila University and Lyceum of the Philippines.
On 8 July 2005 at the Hyatt Regency Hotel in Pasay City, seven Cabinet members, including Boncodin, and three bureau chiefs, announced their withdrawal of support for Arroyo. Collectively known as the “Hyatt 10,” they relinquished their posts in protest of the “Hello, Garci” scandal and called for the resignation of Arroyo, who had allegedly phoned former Commission on Elections chair Virgilio Garcillano to manipulate the 2004 election results in her favor.

On 10 March, Boncodin experienced difficulty in breathing and was admitted to the National Kidney and Transplant Institute (NKTI). She was diagnosed with anemia and end-stage renal disease. Her attending physicians tried to revive her for two hours. On 15 March 2010 at 2:05 p.m., she succumbed to cardiac arrest that resulted from failure of her transplanted kidney. 
Five years ago, Boncodin underwent the transfer operation due to a congenital polycystic kidney. According to NKTI executive director Dr. Enrique Ona, Boncodin's poor compliance with medication as a result of her consultancy jobs overseas caused her body's chronic rejection to the transplanted kidney. Ona added that Boncodin was earlier advised to undergo another kidney transplant to prolong her life. 
Her remains were brought to the Sta. Maria Della Strada Parish in Katipunan, Quezon City.
