There is one competition officially called a “Major League Cup” in football (soccer): the Leagues Cup that matches clubs from Major League Soccer (MLS) with clubs from Mexico’s Liga MX. However, depending on how you interpret “major league cups,” the answer can be framed in a few different ways.

The single “Leagues Cup”

The Leagues Cup is:

  • An annual tournament between MLS teams (USA/Canada) and Liga MX teams (Mexico).
  • Sometimes colloquially referred to as a “Major League Cup” because it involves the “Major League” (MLS), even though its official name is just “Leagues Cup.”

If your question literally means “how many cups are named ‘Major League Cup’?”, the answer is one : the Leagues Cup involving MLS.

How many “major” domestic cups are there in the main leagues?

In common football discussion, people often talk about “major trophies” or “major cups” in the sense of the top domestic and continental competitions. For example:

In England (most typical reference for “major league cups”)

The four major trophies widely recognized in English football are:

  1. Premier League (league title, not a cup but a major trophy)
  2. FA Cup (national cup)
  3. EFL Cup (also known as the League Cup)
  1. UEFA Champions League (top European cup)

So if you’re thinking “how many major cup competitions are there in English football?” the answer is usually two domestic cups :

  • FA Cup
  • EFL Cup (League Cup)

plus the major European cups (Champions League, Europa League, etc.) if you count continent-wide tournaments.

In MLS (North America)

MLS has:

  • MLS Cup – the league championship (playoff final), not a traditional knockout cup but the top trophy.
  • Leagues Cup – the international MLS vs Liga MX tournament.
  • U.S. Open Cup – a nationwide knockout cup in the United States (open to all levels).

Again, if you’re asking specifically about “Major League” (MLS) cups, there are two major cup-style competitions tied to MLS:

  • MLS Cup (championship)
  • Leagues Cup (international tournament)

Quick summary by interpretation

Interpretation of “major league cups”| Answer
---|---
Cups literally named “Major League Cup”| 1 (Leagues Cup, involving MLS) 8
Major domestic cups in English football| 2 (FA Cup + EFL/League Cup) 29
Major trophies in English football (including league & Europe)| 4 (Premier League, FA Cup, League Cup, Champions League) 69
MLS-related cup competitions| 2 (MLS Cup + Leagues Cup) 178

If you meant something more specific (e.g., “in the Premier League,” “in MLS,” or “in world football”), you can clarify and I can narrow this to exactly that context. Information gathered from public forums or data available on the internet and portrayed here.
