The Exit-Entry Permit for Travelling to and from Hong Kong and Macau (Chinese: 往来港澳通行证), colloquially known as a Two-way Permit (Chinese: 双程证) or EEP (Exit-Entry Permit) is issued to Chinese nationals with residency in Mainland China as a travel document for the sole purpose to travel the Chinese Special Administrative Regions of Hong Kong and Macau. The Bureau of Exit and Entry Administration of the Chinese Ministry of Public Security is responsible for the issuing of Two-way Permits and exit endorsements.

Due to the "One country, two systems" policy, Hong Kong, Macau and Mainland Chinese residents who are Chinese citizens cannot use their Chinese, Hong Kong, or Macau passports to enter their respective territories, even though those passports are considered legal valid travel document. The Two-way Permit is the sole travel document for personal visit, family reunion, business, and other non-government purposes to and from the two Chinese Special Administrative Regions. Exceptions are Mainland residents who are transiting to or from a third country or region, as they can use their Chinese passports when entering Hong Kong or Macau for a stay of seven days.

The new version of the permit is changed to a credit-card sized document, which also contains a biometric chip, and was first introduced in Guangdong on May 20, 2014, and later issued nationally on September 15, 2014. The design is similar to the Taiwan Compatriot Permit but the card's color scheme is in light blue. The personal data are directly imprinted on the front of the card while the back of the card contains heat-sensitive ink which are used to print entry endorsements.
