The VIP Protection Unit (Abbreviation: VIPPU; Chinese: 要員保護組), otherwise known as G4 (originally Section G, Division 4) is a protective security unit branch of the Hong Kong Police Force (HKPF).

The original name had been given to the unit since it is the 4th division of the former Royal Hong Kong Police Force's Special Branch (RHKPF Special Branch).

[2] Following the disbanding of the RHKPF Special Branch in 1995, the VIP Unit was reassigned under the Security Wing of the HKPF after the handover in 1997.

It has primary responsibility for the personal safety of HKSAR Chief Executive and his/her core family (previously, the Governor and his family before the handover in 1997), high-rank government officials, VIPs and visiting dignitaries to Hong Kong, therefore the training techniques taught to all VIPPU officers include counter sudden attacks, hostage rescue, VIP protection, and unarmed combat.
