  This report provides detailed findings on the critical laboratory
astrophysics data needs that are required to maximize the scientific return for
NASA's current and near-term planned astrophysics missions. It also provides
prioritized rankings on said laboratory astrophysics data, generally by
waveband. The Report is based on community input gathered at the 2018 NASA
Laboratory Astrophysics Workshop (LAW) from presentations, from discussions
during workshop breakout sessions, and from other solicited input deemed
appropriate by the Scientific Organizing Committee (SOC) obtained prior to and
after the meeting. Hence, the Report is a direct reflection of the spirit and
participant make-up of LAW 2018. The Report also outlines specific
opportunities and threats facing NASA's Laboratory Astrophysics Program, and
articulates concrete actions by which the Agency can capitalize on the
opportunities and mitigate the challenges. The Report was prepared by the SOC,
with help from some invited speakers, and input and review from community
members.
