The 1968 Campeonato Gaúcho was the 48th season of Rio Grande do Sul's top association football league. Grêmio won their 19th title. The league expanded to eighteen teams: the twelve clubs from last season were joined by six teams from last year's Promotion Tournament.[1] [2] It is unknown how these six teams were chosen: Ypiranga, São Paulo, Santa Cruz and São José were among the championship's top six teams, but Cruzeiro and Flamengo were eliminated in the first stage.[3]
The championship's format changed for the first time since 1961 due to its expansion, not without controversy. The league was divided in three stages, as follows:

| Aimoré | 11th | ||
| Brasil | 6th | ||
| Cruzeiro | Eliminated at earlier stages (Second Division) | ||
