no, if two lines are not parallel then the will eventually have to intersect.
Alternate perspective:Yes, if two lines are non-parallel, they need not intersect in three dimensional space.That's the only kind of parallel lines there are, non-intersecting!
In 2D geometry, that is the definition of parallel lines. Two non-intersecting lines are indeed parallel.

Lines in a plane that cross each other are called intersecting lines. When two lines intersect, they do so at a single point, known as the point of intersection. The angles formed at this intersection can vary, and the lines can be either parallel (never intersecting) or non-parallel (intersecting at some angle). Intersecting lines are essential in geometry and help in understanding various concepts such as angles, shapes, and the properties of polygons.

Two lines that are not parallel and do not intersect are skew. If the non-intersecting lines are in the same plane then they are parallel.
Non-intersecting lines in 3-D space may be parallel but need not be.
Intersecting lines. If they have only one point in common, then they are also non-parallel.
Do you mean non intersecting? Because then you might be talking about parallel

A shape with non intersecting lines is 100 percent a parallelogram
If the intersected lines are parallel then the angles are called equal alternate angles
Here are some: They can be (1) coincident, (2) intersecting at one point, (3) coplanar but non-intersecting (ie parallel), (4) non-coplanar, non-parallel and non-intersecting (eg paths of a rail line and of an elevated road going over it - from above, they may appear to intersect but they do not), (5) intersecting at two points (eg longitudes on the earth). etc.
Non-perpendicular intersecting lines. There is no special name.
