Most hated teams

It depends on the age of the 49ers' fan. For me, it's mainly been the Seahawks. Most recently, a new hatred for the Eagles was brewing, but we bodied that organization

90's:

1. Cowpokes
2. Fudgepackers (Leroy Butler was an asshat)

00's:

1. John York

10's:

1. SeaClucks

20's:

1. SeaClucks
2. Beagles

Seahawks
Rams
Cowboys
Eagles
Ravens
Chiefs
GB
Giants

Recency bias says "whoever beat us in the playoffs last"

This Packers fan really has the 49ers living rent free in his head lol.

probably banned from the packer board

1. 90s Cowboys and Carroll/Wilson era Seahawks
2. Current KC team and all thei insufferable people associated with them
3. All Brady/BB cheating teams outside of 1st SB when they beat the rams
4. greatest show on turf rams
5. 90s packers post cowboys

Any one that grew up watching the team in its glory years will say

1) Dallas
2) GB
3) NYG

All three of these teams may have cost us anywhere from 3 to 5 Superbowls in that era. If you're a native Bay Area fan, you'll likely put the Raiders on that list, somewhere at number 3 or below (can't imagine them being on the 1 or 2 spot).

If you're a younger fan that grew up in the 00s, then I'm sure Seattle is number one on that list given the heartbreaks we've endured in the better half of the past decade. LA is likely a close second, and maybe Dallas at number 3 because of the "history" you've heard about when these teams play.

I can't forgive Dallas for 92 and 93. I can't forgive GB for 95 and 97 (they were better than us in 96), and I can't forgive NY for stopping the 3 peat.

If your first answer isn't dallas then

You thought SEA was bad, and they were, you should have been around for the jimmy led Miami hurricane 2.0 Cowboys …and they were awesome which made it worse

1. Rams - the longtime division rival
2. Cowboys - both teams were the NFL's best in the early to mid 90s
3. Packers - replaced the Cowboys as the Niner playoff nemesis
4. Seahawks - owned the Harbaugh era Niners

this packers fan is now obviously a niners fan

Dallas

Raiders (fanbase rivalry from growing up in the Bay)
Tie: Seahawks, Packers, Giants

Pretty much this! Though I'd add the Steelers to every decade thanks to geography and their fans
