Palace of the Fans was a Major League baseball park located in Cincinnati, Ohio. It was the home of the Cincinnati Reds from 1902 through 1911. The ballpark was on an asymmetrical block bounded by Findlay Street (south), Western Avenue (northeast, angling), York Street (north) and McLean Avenue (west).

The "Findlay and Western" intersection was the home field of the Reds from 1884 through June 24, 1970, when the team moved to Riverfront Stadium. The location of the diamond and consequently the main grandstand seating area was shifted several times during the 86½ seasons that the Reds played there. The Palace of the Fans was actually the second of three parks that stood on the site:

On May 28, 1900, the southwest grandstand of League Park, the home of the Reds since their days in the American Association, burned to the ground. The Reds were forced to spend most of May and June on the road while League Park was reconfigured to move the diamond back to its old location in the southeast corner.

After a season of playing in the southeast corner, Reds owner John Brush announced the club would build a new grandstand for the next season. The project started ambitiously in the spring of 1901. The term "Palace of the Fans" first appeared in March. The club hoped to have the new stands ready by summer, but various delays set the opening back to spring of 1902, so the entire 1901 season was also spent at the southeast corner.

The Palace of the Fans, so audaciously named, also presented a striking appearance. Designed in a neo-classic style reminiscent of Chicago's World's Columbian Exposition of 1893, the Palace featured an extravagant facade, with 22 hand-carved Corinthian columns with elaborate details at the top, and opera-style private boxes in front of the covered grandstand. The grandstand actually sat atop carriage stalls so that the wealthy could simply drive directly to the game, an early precursor of "luxury suites". It was built mostly of concrete, and was the second park (after Baker Bowl in Philadelphia) to use concrete for the bulk of its construction.

The grandstand was unique: a blend of Roman and Greek styling that had never been used before in a grandstand, and has never been seen since. The 3,000-seat grandstand featured 19 "fashion boxes" along the front railing that could hold 15 or more well-to-do fans. Beneath the grandstand, at field level, was standing room for 640 more spectators in a rowdy section known as "Rooter's Row." This section was so close to the players, the fans could take part in on-field conversations. Rooters Row was also strategically placed by the bar. The facade behind home plate contained the word "CINCINNATI". This was obviously of no benefit to anyone in attendance, assuming they knew where they were, but it ensured that pictures of the stands would inform viewers. However, the designers of the park forgot to include dugouts or clubhouses for the players.

The original 1884 stand remained as right field seating, having escaped the fire. A less elaborate stand connected the old and the new structures. Both the contemporary club owners and modern baseball historians consider the 1902 structure to be a new ballpark. Cincinnati fans not interested in the hype continued to call the facility League Park, hence the alternate historical name, "League Park III". Newspapers used the two names interchangeably, along with the occasional variant Fans' Palace.

On Opening Day, April 17, 1902, some 10,000 spectators crowded into the park and watched the Reds lose to the Chicago Colts (a.k.a. "Cubs"), 6-1.
