Century II Convention Hall, Convention center in Wichita, Kansas.

Century II is a convention center in Wichita with multiple event spaces designed to host conferences, exhibitions, and performances. The facility contains meeting rooms of varying sizes, a concert hall, and an exhibition area all within the same building complex.

Designed by John M. Hickman, an apprentice of Frank Lloyd Wright, Century II opened on January 11, 1969, for the centennial of Wichita's 1870 incorporation. It replaced The Forum, an exposition hall from 1911 that had become outdated. The Bob Brown exhibit hall was added in 1986, and the building was listed on the National Register of Historic Places in 2020.

Century II is the home venue of the Wichita Symphony Orchestra, Wichita Grand Opera, Music Theatre Wichita and Music Theatre for Young People. Music Theatre Wichita stages Broadway-scale summer musicals here, and its Century II productions have featured Kristin Chenoweth, Kelli O'Hara and Ashley Park. The 1926 Wurlitzer organ from New York's Paramount Theatre, moved here in the 1970s, is still played at concerts.

Century II sits between Douglas Street and Waterman Street near the east bank of the Arkansas River in downtown Wichita. The 303-room Hyatt Regency Wichita, built in 1997, connects directly to the building. The lobby rings the main level, with the convention hall, exhibition hall and concert hall in wedge-shaped sections inside the ring, and the stages of the three spaces meet at the center.

The building's shape carries a family story: architect John M. Hickman's daughter Susan said he took the sand-colored pillars from Kansas wheat fields and the pale blue dome from the open sky. Hickman had trained under Frank Lloyd Wright at Taliesin West in the late 1940s, and the low circular plan with its shallow dome recalls Wright's Marin County Civic Center.
