The San Francisco 49ers have a rich history filled with lots of success, which has led to a lot of rivalries against other good football teams.

Let's break down the 49ers' five biggest rivals in their history.

5. Oakland Raiders

The Oakland Raiders and 49ers rivalry all has to do with how close the teams were to each other. With the Raiders moving to Las Vegas, the rivalry might lose a little luster, but it can't take away from what has already happened.

There hasn't been one big matchup that led to the rivalry, but it seems every time the two teams step on the field, there are fireworks. These are two teams who had a benches-clearing brawl during the preseason.

4. St. Louis/Los Angeles Rams

The rivalry with the Rams lost a little luster when they moved to St. Louis, but it's going to really heat back up with the two teams back in the same state.

Back in 1989, the San Francisco 49ers gave the Rams the business. The 49ers dominated on both sides of the field on the way to a 30-3 victory. The Rams and 49ers play at least twice a year, which leaves plenty of opportunities for big-time games.

The 49ers and Rams have faced off 141 times, with one of those coming in the postseason.  The 49ers have won 71 times which gives them the lead in the series by four wins.

3. Green Bay Packers

The Green Bay Packers and 49ers rivalry was alive and well in the 1990s, and it could be making a comeback now. Even though it was a rivalry, it was real one-sided in the Packers' favor.

One of the most memorable games in history was in 1998 when a young Terrell Owens made a touchdown catch to seal the game. That was the start of the buzz around Owens, and soon after he was called TO.

The Packers and 49ers have met 69 times throughout their history. The Packers won 36 times, the 49ers have won 32 times, and one game ended in a tie.

2. Seattle Seahawks

The Seattle Seahawks and 49ers rivalry is one that is more recent, but it is superheated. The real start of these two teams becoming a rivalry was when Colin Kaepernick and Russell Wilson were under center for their respective teams. It seemed every time during the regular season and playoffs when the two squads faced off, there were fireworks.

The most memorable game between these two teams was in 2014 in the NFC Championship game. The game was back and forth with a lot of chirping throughout the game. Richard Sherman sealed the game for the Seahawks with an interception. After the game, Sherman had one of the more memorable interviews ever when he ripped Michael Crabtree.

The Seahawks and 49ers have matched up 43 times with Seattle winning 26 times. The only time the two teams faced off in the postseason was in 2014.

1. Dallas Cowboys

As of late, the Dallas Cowboys and San Francisco 49ers rivalry is still intense, but most of the big-time battles happened over ten years ago.

Back in the 1970s, the Cowboys knocked the 49ers out of the playoffs, and that was the real start of the rivalry. Everyone remembers the 1982 meeting in the NFC Championship with “The Catch” in the back of the end zone that propelled the 49ers into the Super Bowl. The Cowboys also beat the 49ers a couple of times on the way to Super Bowl victories.

The Cowboys and 49ers have played 36 times, and Dallas leads the series 18-17-1. In the postseason, the Cowboys lead the series 5-2. The largest victory for either side was back in 1980 when the Cowboys captured a 59-14 victory against the 49ers.
