git-svn

From the official documentation (https://git-scm.com/docs/git-svn):

NAME git-svn - Bidirectional operation between a Subversion repository and Git

SYNOPSIS git svn <command> [options] [arguments]

DESCRIPTION git svn is a simple conduit for changesets between Subversion and Git. It provides a bidirectional flow of changes between a Subversion and a Git repository.

git svn can track a standard Subversion repository, following the common "trunk/branches/tags" layout, with the --stdlayout option. It can also follow branches and tags in any layout with the -T/-t/-b options (see options to init below, and also the clone command).

Once tracking a Subversion repository (with any of the above methods), the Git repository can be updated from Subversion by the fetch command and Subversion updated from Git by the dcommit command.
