TMZ Sports has learned ... the Golden State Warriors star summoned Bay Area tattoo artist Nino Lapid to his home Tuesday night for a Curry family ink session.

Curry got Hebrew letters tatted on his arm -- but we're not exactly sure what the message was. Guessing it says something about destroying the Cavs?!?

Steph's dad Dell also went with a message on his wrist ... while his wife, Ayesha, also got some body art -- though her tat is also secret for now.

Steph's sister and mom were also at the home for the needle sesh. No word if they participated.

Win a ring, get new ink, repeat.
