Best BJJ Gyms in Vienna: What Reddit Says

Vienna has a deeper BJJ scene than most traveling grapplers expect. Six gyms surface repeatedly when locals are asked where to train on r/bjj and r/wien. Here is what they actually said, sourced and dated.

Verdict at a Glance

Data from bjjgym.com gym directory and Reddit mention tracking.

ZR TEAM VIENNA

The most detailed gym write-up from a Vienna local came in a 2023 r/bjj thread:

“I train at zrteam vienna - which is pretty central. Our headcoach is a three stripe black belt, and three more black belts, bunch of brownbelts and purple. we have a small but really good comp team (which i am also a part of), and we compete nationally and internationally (recent Euros 23). The classes are both gi and no gi, also some wrestling and open mats on saturday. The overall vibe of the gym is pretty chill, but we roll hard still cautious. We also have a weights area and the gym can be accessed also outside of class hours. The fees are on the upper range for austria (96 for…” source, 2023

A separate commenter who had visited multiple Vienna gyms in 2024 described the crowd as “v nice, more white-collar hobbyists with good technique.” source, 2024

ZR Team is one of the six schools named in the definitive r/wien grappling recommendation thread from September 2024. source, 2024

BJJ Wien - Science of Jiu Jitsu (SOJJ)

SOJJ collected the most raw mention count of any Vienna gym in this data set and landed three separate named recommendations across r/bjj and r/jiujitsu in 2024 alone.

“For BJJ: Science of Jiujitsu or ATOS.” source, 2024

“Come to Science of Jiu Jitsu in Vienna” source, 2024

The September 2024 r/wien thread also noted: “Science of Jiu Jitsu has a free Open Mat every othe[r week].” source, 2024

The directory lists SOJJ as no-gi only (gi: no, nogi: yes). Confirm before arriving in a kimono.

Atos Jiu Jitsu Vienna

ATOS comes up alongside SOJJ as the other top pick for BJJ. In the same September 2024 r/wien thread:

“For BJJ: Science of Jiujitsu or ATOS.” source, 2024

A second r/wien commenter in August 2024 noted that a friend trains at Atos Jiu Jitsu and is “ganz zufrieden” (quite satisfied). source, 2024

ATOS Vienna also operates an affiliate: HIRO (hirogym.at). The same September 2024 recommender called HIRO “the best overall package” for anyone the location suits. source, 2024

Roger Gracie Vienna BJJ

The head instructor described their history in a 2020 r/bjj thread - a timeline worth knowing before you walk in:

“I started BJJ in Munich when i graduated high school… I moved to Vienna, Austria after and continued training there. I held every belt pretty much 3 years. Austrian BJJ and grappling was in the dark ages back then and is still around 10 years behind which was tough at times but despite this we managed to build a strong team. If you ever find yourself travelling to Vienna, stop by our academy Roger Gracie Vienna.” source, 2020

A 2021 r/wien thread on the best BJJ gyms in the city grouped Roger Gracie with Alpha as the top gi recommendation:

“For BJJ, Roger Gracie and Alpha Academy.” source, 2021

The directory tags this gym as high-level with drop-in, open mat, kids classes, and women’s classes.

Alpha Jiu-Jitsu

Alpha surfaces consistently across Vienna BJJ threads from 2019 through 2024, always grouped with ZR Team and Roger Gracie as an established option.

“ZR Gym or Alpha jiu Jitsu are well known gyms in vienna.” source, 2019

“For BJJ, Roger Gracie and Alpha Academy.” source, 2021

A 2024 r/judo comment specifically flagged Alpha for combining judo, wrestling, and BJJ - useful if you want standup integrated into your training. source, 2024

Alpha operates two locations: Nordbahnstraße 16 (central) and Barbara-Prammer-Allee 13 in Seestadt. The Nordbahnstraße location has drop-in confirmed in the directory.

City Thong

The name is memorable. The gym holds up. A Redditor who had sampled multiple Vienna gyms and settled on City Thong as their home base wrote in 2024:

“City Thong. Hilarious name. Great gym though. And tons of space, so you can work standup, which isn’t possible at all gyms.” source, 2024

An earlier recommendation from 2014 was enthusiastic - though that is now over a decade old and may not reflect current operations:

“I’m training at Citythong in Vienna and can highly recommend it. They are only closed on the 1st (which is a public holiday), but open from the 2nd on… There is also Backyard which is a Roger Gracie affiliate, another good option.” source, 2014

The directory currently lists City Thong with drop-in: no and no confirmed gi/no-gi data. Verify schedules and policies directly before visiting.

Also Worth Knowing

Vienna Grappling Club (Barmherzigengasse 17) accepts drop-ins, offers gi and no-gi, and carries one of the strongest tag sets in the directory: high-level, affordable, open mat, beginner-friendly, clean, shower. No direct named quotes surfaced in this data set. full profile

Vienna Combat Academy (Stadlauer Str. 4) is tagged as affordable, high-level, and beginner-friendly with drop-in and open mat. The directory also flags it as “disorganized” - factor that in. full profile

Black Tiger MMA (Mendelssohngasse 7) accepts drop-ins and offers gi and no-gi. Directory tags: high-level, women’s classes, friendly atmosphere, beginner-friendly, clean. full profile

KaiGym was flagged in 2021 as the top no-gi address in Vienna: “Pure no-gi KaiGym is probably the best address (3 Luta Livre blackbelts, lots of competitors, very technical).” source, 2021 That assessment is from 2021; KaiGym is not currently listed in the bjjgym.com directory.

Best for You

Visiting and need a confirmed drop-in: ZR TEAM VIENNA, SOJJ, and ATOS all list drop-in as available. SOJJ also runs a free open mat on alternating weeks.

Training to compete: ZR Team ran a competition squad to Euros 2023 with a documented coaching staff. A 2021 r/wien commenter also named CageWolves MMA and Iron Fist as “the most active” competition gyms at that time, though that data is a few years old.

No-gi only: SOJJ lists no-gi only in the directory. KaiGym was the community pick for pure no-gi in 2021 but is not in the directory.

Just starting: Roger Gracie Vienna, Vienna Combat Academy, and Black Tiger MMA all carry beginner-friendly tags. Roger Gracie also has women’s classes and kids classes listed.

Gi BJJ with judo cross-training: Alpha Jiu-Jitsu, specifically noted in 2024 for combining the three disciplines.
