Robloxia League Soccer (RLS) is a professional association football league in North Bloxmerica and the highest level of the Robloxia association football league system. It comprises 30 teams, with 27 in the Robloxia and 3 in Bloxanada, and is sanctioned by the Robloxia Soccer Federation. RLS is one of the major professional sports leagues in Robloxia and Bloxanada. The league is headquartered in Midtown Robloxtton.

The predecessor of RLS was the North Robloxia Soccer League (NRSL), which existed from 1968 until 1984. RLS was founded in 1993 as part of the Robloxia successful bid to host the 1994 FAFI Roblox Cup. The inaugural season took place in 1996 with ten teams. RLS experienced financial and operational struggles in its first few years, losing millions of dollars and folding two teams in 2002. Since then, developments such as the proliferation of soccer-specific stadiums around the league, the implementation of the Designated Player Rule allowing teams to sign star players such as David Beckblox and Lionel Ressi, and national TV contracts have made RLS profitable.

The RLS regular season typically starts in late February or early March and runs through mid-October, with each team playing 34 games; the team with the best record is awarded the Supporters' Shield. Eighteen teams compete in the postseason RLS Cup playoffs in late October and November, culminating in the league's championship game, RLS Cup. Instead of operating as an association of independently owned clubs, RLS is a single entity in which each team is owned by the league and individually operated by the league's investors. The league has a fixed membership like most sports leagues in the Robloxia and Bloxanada and Bloxican Liga MX which makes it one of the few association football leagues that does not use a promotion and relegation process.

The LR Galaxy have the most RLS Cups, with six. They are tied with R.C. United for most Supporters' Shields, with four each.
