Liberty State Delivery (LSD) is a delivery, and possibly postal, company presumably servicing Liberty City and Liberty State in Grand Theft Auto IV and Grand Theft Auto: Chinatown Wars.

The organization has no prominence in GTA IV, with next to no role in any of the games' storylines. However, it is prevalently based in a large public building (resembling the James Farley Post Office) in Middle Park East, Algonquin, while certain Yankee trucks feature the LSD corporate logo.

Trivia

• Like Los Santos Delivery and the Liberty Sanitation Department, the Liberty State Delivery's abbreviation references lysergic acid diethylamide, a hallucinogenic drug commonly known as LSD.
• The company's logo looks somewhat like a swastika.
• The company's possible rivals are Alpha Mail and Post Op. They all use a different type of truck (LSD = Yankee, Alpha Mail = Mule, Post Op = Benson).
• Sometimes you can see a mailman on the streets.

But it's pretty rare to see them.

WAREHOUSES:

Liberty State Delivery has a Holding Warehouse in Port Tudor. They are also known to have an unused warehouse in the Broker Industrial Yard in East Broker.
