World Market Center Las Vegas, Convention center in downtown Las Vegas, Nevada, US.

The World Market Center Las Vegas is a furniture showroom complex of 5.3 million square feet on a 57-acre site beside Interstate 15 in downtown Las Vegas. Its four buildings include Building A, a 10-story structure whose facade carries a swooping arc of reflective metal panels, and the 16-story Buildings B and C. Metal letters reading "WORLD MARKET CENTER" sit along the top edge of the ridged grey facade.

Conceived by Shawn Samson and Jack Kashani of Furniture Mart Enterprises, the project was unveiled in February 2001 on 57 acres beside Interstate 15, land owned by Union Pacific Railroad. Ground was broken on March 21, 2003, and Building A opened on July 25, 2005, hosting the first Las Vegas Market. Buildings B and C followed in January 2007 and July 2008; after the 2008 recession shelved further phases, ownership merged with High Point rivals in 2011 to form International Market Centers. The Expo building, funded partly by $30 million in city tax increment financing, opened on April 9, 2021.

The Las Vegas Market happens twice yearly and draws designers, retail buyers, and wholesalers from the furniture industry together. This event shapes the year for many professionals in this sector.

The complex sits at 495 S. Grand Central Parkway beside Interstate 15, with Buildings A, B and C and the Expo building on one 57-acre site. A seven-level garage north of Building C holds 3,600 vehicles. Outside market weeks, the Las Vegas Design Center occupies the first two floors of Buildings A and B and the first three of Building C, open Monday to Friday to trade members.

The first Las Vegas Market in July 2005 drew so many attendees that three large tent pavilions were used alongside the Las Vegas Convention Center; Guinness World Records listed the tent structure as the largest in the United States. Building A had been fully leased more than a year before opening, with 230 tenants signed.
