Malacañang Palace, Presidential palace in San Miguel, Philippines

Malacañang Palace is a presidential residence in San Miguel, Philippines, positioned along the northern bank of the Pasig River. The building follows Spanish colonial architecture with decorated inner courtyards, arches, and window grilles characteristic of this construction style.

Don Luis José de la Rocha Camiña, a Spanish physician in the galleon trade, built the original stone country house in 1750 with his wife Gregoria Tuason de Zaballa. After the 3 June 1863 earthquake destroyed the Palacio del Gobernador in Intramuros, it became the official seat of the Spanish governors-general; General Wesley Merritt was the first American governor to reside there after 1898.

The name is usually traced to the Tagalog mamalakáya, "fisherman", via Mamalakáya-han, "place of the fisherman", later simplified by Spanish authorities. A rival account, recorded in the 1930s, derives it from "May lakan diyan"; the Rocha family instead links it to a guard's phrase "malaki iyan". Spanish-era books spelled it Malacañang, the Americans changed it to Malacañan, and Ramon Magsaysay restored Malacañang in 1953.

The compound includes several structures with guesthouses, government offices, and Kalayaan Hall, which serves as a historical museum. Visitors should check access rules in advance, as certain areas open only during specific hours.

Malacañang was the only major government building in Manila to survive the heavy artillery bombing of the Second World War, and the San Miguel district around it was likewise spared. The palace appears on the reverse side of the 20-peso banknote.
