Designed by painter Nguyen Du of the Vietnam Post Corporation, the set includes two stamps measuring 37 x 37 millimetres.
The first design, priced at VND3,000 features a father monkey walking proudly among peach blossoms, promising a new year of health and success.
Meanwhile the second design priced at VND10,500 portrays a mother monkey and her child hugging each other, representing love, compassion and warmth of the family.
According to painter Nguyen Du, the family of monkeys symbolise the gathering of all Vietnamese families on Tet holiday.
The main colours used in the two stamps are bright yellow and pink, representing apricot and peach flowers, two iconic blossoms of Vietnamese people on the Lunar New Year, he said.
